Advanced tools
Format an OpenAPI document by ordering, formatting and filtering fields.
Format an OpenAPI document by ordering, formatting and filtering fields.
The openapi-format CLI can load an OpenAPI file, sorts the OpenAPI fields by ordering them in a hierarchical order, format the casing of the fields and can output the file with clean indenting, to either JSON or YAML.
Next to the ordering & formatting, the CLI provides additional options to filter fields & parts of the OpenAPI document based on flags, tags, methods, operationID's and even unused components.
The openapi-format CLI has the option to convert an OpenAPI 3.0 document to an OpenAPI version 3.1.
Public documentation: An OpenAPI document is a specification that evolves and changes. To facilitate working with the specification and publishing the document as public documentation, you want to deliver a clean and structured specification. OpenAPI-format helps you to organize the fields by sorting, formatting and filtering specific elements from the OpenAPI like internal endpoints, beta tags, ... and even unused schemas, examples, responses, ... with a clean and optimized OpenAPI document as a result.
Maintenance: When working on large OpenAPI documents or with multiple team members, the file can be become messy and difficult to compare changes. By sorting & formatting from time to time, the fields are all ordered in a structured manner & properly cased, which will help you to maintain the file with greater ease.
CI/CD pipelines: OpenAPI-format can be useful in CI/CD pipelines, where the OpenAPI is used as the source for other documents like Web documentation, Postman collections, test suites, ...
The OpenAPI-Format Playground is a web-based tool for formatting and sorting OpenAPI documents, powered by the openapi-format CLI.
More info about the features and usage, can be found in the readme.
While possible to install globally, we recommend that you add the openapi-format CLI to the node_modules by using:
$ npm install --save openapi-format
or using yarn...
$ yarn add openapi-format
Note that this will require you to run the openapi-format CLI with npx openapi-format your-openapi-file.yaml or, if
you are using an older versions of npm, ./node_modules/.bin/openapi-format your-openapi-file.yaml.
$ npm install -g openapi-format
To execute the CLI without installing it via npm, use the npx method
$ npx openapi-format your-openapi-file.yaml

The CLI will sort the OpenAPI document in the defined order liked defined per OpenAPI key/field/property/element. The fields that are not specified will keep their order like it is in the original OpenAPI document, so only defined fields will be re-ordered.
The default sorting of the different fields based on the defined order (listed in the table below), which is stored in the defaultSort.json file.
You can easily modify this by specifying your own ordering per key, which can be passed on to the CLI (see below for an example on how to do this).
| Key | Ordered by | OpenAPI reference |
|---|---|---|
| root | - openapi - info - servers - paths - components - tags - x-tagGroups - externalDocs | openapi-object |
| get | - operationId - summary - description - parameters - requestBody - responses | operationObject |
| post | - operationId - summary - description - parameters - requestBody - responses | operationObject |
| put | - operationId - summary - description - parameters - requestBody - responses | operationObject |
| patch | - operationId - summary - description - parameters - requestBody - responses | operationObject |
| delete | - operationId - summary - description - parameters - requestBody - responses | operationObject |
| parameters | - name - in - description - required - schema | parameterObject |
| requestBody | - description - headers - content - links | request-body-object |
| responses | - description - headers - content - links | responses-object |
| content | (By alphabet) | responses-object |
| components | - parameters - schemas | components-object |
| schema | - description - type - items - properties - format - example - default | schemaObject |
| schemas | - description - type - items - properties - format - example - default | |
| properties | - description - type - items - format - example - default - enum |
Have a look at the folder yaml-default and compare the "output.yaml" (sorted document) with the "input.yaml" (original document), to see how openapi-format have sorted the OpenAPI document.
You can change the order of the paths defined in the OpenAPI specification and sort them alphabetically (path) or by the first tag of the first method (tags).
Options to sort by:
original (default): keep the order as defined in the OpenAPI specificationpath: order the paths alphabetically by the path partstags: order by the first tag of the first method| Key | Options | OpenAPI reference |
|---|---|---|
| sortPathsBy | 'original' / 'path' / 'tags' | paths-object |
By specifying the desired filter values for the available filter types, the openapi-format CLI will strip out any matching item from the OpenAPI document. You can combine multiple types to filter out a range of OpenAPI items.
For more complex use-cases, we can advise the excellent https://github.com/Mermade/openapi-filter package, which has extended options for filtering OpenAPI documents.
| Type | Description | Type | Examples |
|---|---|---|---|
| methods | OpenAPI methods. | array | ['get','post','put'] |
| inverseMethods | OpenAPI methods that will be kept | array | ['get','post','put'] |
| tags | OpenAPI tags | array | ['pet','user'] |

Some more details on the available filter types:
=> methods: Refers to the Path Item Object
This will remove all fields and attached fields that match the verbs. In the example below, this would mean that
all get, put, post items would be removed from the OpenAPI document.
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
summary: Finds Pets by status
put:
summary: Update an existing pet
=> inverseMethods: This option does the inverse filtering, by keeping only the verbs defined and remove all other verbs.
=> tags: Refers to the "tags" field from the "Operation Object" https://spec.openapis.org/oas/v3.0.3.html#operationObject
This will remove all fields and attached fields that match the tags. In the example below, this would mean that all
items with the tags pet or user would be removed from the OpenAPI document.
For example:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
put:
tags:
- pet
summary: Update an existing pet
=> inverseTags: This option does the inverse filtering, by keeping only the tags defined and remove all other tags, including the operations without a tags.
=> operationIds: Refers to the "operationId" field from the Operation Object
This will remove specific fields and attached fields that match the operation ID's. In the example below, this would
mean that the item with operationID findPetsByStatus would be removed from the OpenAPI document.
For example:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
operationId: findPetsByStatus
=> inverseTags: This option does the inverse filtering, by keeping only the operationIds defined and remove all other operationIds, including the operations without an operationId.
=> operations: Refers to a combination of a OpenAPI method & path from the Path Object & Path item
This will remove specific path items that match the operation definition PUT::/pets. In the example below, this would
mean that the item with the path '/pets' and method 'PUT' would be removed from the OpenAPI document.
For example:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
summary: Finds Pets by status
put:
summary: Update an existing pet
An operationId is an optional property. To offer support for OpenAPI documents that don't have operationIds, we have
added the operation definition which is the unique combination of the OpenAPI method & path, with a :: separator
symbol.
This will allow filtering for very specific OpenAPI items, without the need of adding operationIds to the OpenAPI document.
To facilitate managing the filtering, we have included wildcard options for the operations option, supporting the
methods & path definitions.
REMARK: Be sure to put quotes around the target definition.
Strict matching example: "GET::/pets"
This will target only the "GET" method and the specific path "/pets"
Method wildcard matching example: "*::/pets"
This will target all methods ('get', 'put', 'post', 'delete', 'options', 'head', 'patch', 'trace') and the specific
path "/pets"
Path wildcard matching example: "GET::/pets/*"
This will target only the "GET" method and any path matching any folder behind the "/pets", like "/pets/123" and
"/pets/123/buy".
Method & Path wildcard matching example: "*::/pets/*"
A combination of wildcards for the method and path parts is even possible.
=> flags: Refers to a custom property that can be set on any field in the OpenAPI document.
This will remove all fields and attached fields that match the flags. In the example below, this would mean that all
items with the flag x-exclude would be removed from the OpenAPI document.
For example:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
x-exclude: true
=> inverseFlags: This option does the inverse filtering, by keeping only the operations, components, tags, x-tagGroups that match the flag(s). This is a very aggressive option to keep only the items that are needed.
=> flagValues: Refers to a flag, custom property which can be set on any field in the OpenAPI document, and the combination with the value for that flag.
This will remove all fields and attached fields that match the flag with the specific value.
A flagValues example:
flagValues:
- x-version: 1.0
- x-version: 3.0
In the example below, this would mean that all items with the flag x-version that matches x-version: 1.0 OR x-version: 3.0 would be removed from the OpenAPI document.
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
x-version: 1.0
The filter option flagValues also will remove flags that contain an array of values in the OpenAPI document.
A flagValues example:
flagValues:
- x-versions: 1.0
- x-versions: 2.0
In the example below, this would mean that all items with the flag x-versions, which is an array, that match x-version: 1.0 OR x-version: 3.0 would be removed from the OpenAPI document.
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
x-versions:
- 1.0
- 3.0
- 5.0
Have a look at flagValues and flagValues for array values for a practical example.
=> inverseFlagValues: This option does the inverse filtering, by keeping only the operations, components, tags, x-tagGroups that match the flag with the specific value. This is a very aggressive option to keep only the items that are needed.
=> ResponseContent: Refers to the Response Object's content
A responses content filter example:
responseContent:
- application/json
This will remove all the content that match the media types from the responses. In the example below, this would mean that all application/json
content items would be removed from the OpenAPI document
Example before:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pet:
post:
tags:
- pet
summary: Add a new pet to the store
description: Add a new pet to the store
operationId: addPet
x-visibility: true
responses:
'200':
description: Successful operation
content:
application/xml:
schema:
$ref: '#/components/schemas/Pet'
application/json:
schema:
$ref: '#/components/schemas/Pet'
'405':
description: Invalid input
Example after:
openapi: 3.0.0

x-visibility: true
responses:
'200':
description: Successful operation
content:
application/xml:
schema:
$ref: '#/components/schemas/Pet'
'405':
description: Invalid input
=> inverseResponseContent: This option does the inverse filtering, by keeping only the content with media types defined and remove all other content.
=> requestContent: Refers to the Request Body Object's content
A request body content filter example:
requestContent:
- application/json
This will remove all the content that match the media types from the request body. In the example below, this would mean that all application/json
content items would be removed from the OpenAPI document.
Example before:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pet:
post:
tags:
- pet
summary: Add a new pet to the store
description: Add a new pet to the store
operationId: addPet
x-visibility: true
requestBody:
content:
application/xml:
schema:
$ref: '#/components/schemas/Pet'
application/json:
schema:
$ref: '#/components/schemas/Pet'
Example after:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pet:
post:
tags:
- pet
summary: Add a new pet to the store
description: Add a new pet to the store
operationId: addPet
x-visibility: true
requestBody:
content:
application/xml:
schema:
$ref: '#/components/schemas/Pet'
=> inverseRequestContent: This option does the inverse filtering, by keeping only the content with media types defined and remove all other content types from the request body.
=> unusedComponents: Refers to a list of reusable component types, from which unused items will be removed.
This option allows you to strip the OpenAPI document from any unused items of the targeted components types.
Any item in the list of OpenAPI components that is not referenced as $ref, will get marked and removed from the OpenAPI document.
REMARK: We will recursively strip all unused components, with a maximum depth of 10 times. This means that "nested" components, that become unused, will also get removed
Supported component types that can be marked as "unused":
=> textReplace: "search & replace" option to replace text in the OpenAPI specification
The textReplace provides a "search & replace" method, that will search for a text/word/characters in the OpenAPI description, summary, URL fields and replace it with another text/word/characters.
This is very useful to replace data in the OpenAPI specification.
A textReplace example:
textReplace:
- searchFor: 'Pets'
replaceWith: 'Dogs'
- searchFor: 'swagger.io'
replaceWith: 'openapis.org'
This will replace all "Pets" with "Dogs" & "swagger.io" with "openapi.org" in the OpenAPI document.
=> stripFlags: Refers to a list of custom properties that can be set on any field in the OpenAPI document.
The stripFlags will remove only the flags, the linked parent and properties will remain. In the example below, this would mean that all
flags x-exclude itself would be stripped from the OpenAPI document.
Example before:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
x-exclude: true
summary: Finds Pets by status
Example after:
openapi: 3.0.0
info:
title: API
version: 1.0.0
paths:
/pets:
get:
summary: Finds Pets by status
=> preserveEmptyObjects: Refers to any properties of your OpenAPI document, from which empty object values would be kept.
The preserveEmptyObjects will preserve all empty objects if set to true.
You can also pass a list of keys from which preserve empty objects. For instance a ['schema'] value would only prevent removal of empty objects having for key schema.
REMARK: Please note that openapi-format default behavior is to remove all empty objects from your document, except for items of examples, security, schemas, default, oneOf, allOf.
openapi: 3.0.0

Tools like spectral or speccy, or any of the linting tools, provide a manner to validate & lint OpenAPI specifications to be uniform. The linting tool informs about the incorrect usage of OpenAPI properties & inconsistent field names. This is very useful and helps to guard the quality of the OpenAPI specification. They inform which fields to correct so that the specification will comply with all the defined linting rules.
The openapi-format CLI formatting option can assist with keeping the field names consistent by automatically changing the casing of the properties/keys/names for the different elements in the OpenAPI document. The desired casing can be defined per OpenAPI key/element (see list below). The keys that are not specified will keep their casing like it is in the original OpenAPI document, so only for defined fields, the casing will be changed.

The casing options are provided by the nano NPM case-anything package.
=> operationId: Refers to the operationId properties in the OpenAPI document.
Formatting casing example:
operationId: kebab-case
Example before:
openapi: 3.0.3
paths:
/pets:

Example before:
openapi: 3.0.3
paths:
/orders:
get:

pet_model:
type: object
openapi-format will format all the component keys like: "userModel", "order-model", "pet_model" to PascalCase, including formatting all the "$ref" used in the OpenAPI document.
Example after:
openapi: 3.0.3
paths:

=> componentsParametersCookie / componentsParametersPath / componentsParametersQuery / componentsParametersHeader: Refers to "name" in the Parameters types: Path, Query or Header, which can be defined inline in the Path or as a reference in the components of the OpenAPI document.
Formatting casing example:
componentsParametersPath: kebab-case
Example before:
openapi: 3.0.3
paths:
'/pet/{petId}':
get:
parameters:
- name: petId
in: path
description: ID of pet to return
- $ref: '#/components/parameters/LimitParam'
components:
parameters:
LimitParam:
name: limitParam
in: query
description: max records to return
The CLI will format the "name" of the parameters: Path, Query or Header like: "petId", "limitParam" to kebab-case in the OpenAPI document.
Example after:
openapi: 3.0.3
paths:
'/pet/{petId}':
get:
parameters:
- name: pet-id

$ openapi-format openapi.json -o openapi-formatted.json
$ openapi-format https://raw.githubusercontent.com/OAI/OpenAPI-Specification/main/examples/v3.0/api-with-examples.json -o openapi-formatted.json
$ openapi-format openapi.json -o openapi.yaml
$ openapi-format openapi.json --json
$ openapi-format openapi.json --yaml
$ openapi-format openapi.json -o openapi.yaml
$ openapi-format openapi.json -o openapi-formatted.json --no-sort
This should keep the OpenAPI fields in the same order. This can be needed, when you only want to do a filtering or rename action.
$ openapi-format openapi.yaml -o openapi-3.1.yaml --no-sort --convertTo "3.1"
This will convert the OpenAPI 3.0 document into version 3.1 of OpenAPI, without any ordering or filtering. During the conversion, openapi-format will transform all OpenAPI 3.0 properties into the OpenAPI 3.1 properties, as described in the migration guide from Phil Sturgeon.
$ openapi-format openapi.json -o openapi-formatted.json --sortComponentsFile ./test/json-sort-components/customSortComponents.json
This will sort all elements in the components ( components/schemas, components/parameters, components/headers, components/requestBodies, components/responses, ...) section by alphabet.
When you want to strip certain methods ,tags, operationIds, operations, flags you can pass a filterFile which contains the
specific values for the methods ,tags, operationIds, operations, flags.
This can be useful to combine with the sorting, to end up with an order and filtered OpenAPI document.
example:
$ openapi-format openapi.json -o openapi-formatted.json --filterFile customFilter.yaml
where the customFilter.yaml would contain a combination of all the elements you want to filter out.
flags:
- x-visibility
flagValues: [ ]
tags: [ ]
operationIds:
- addPet
- findPetsByStatus
During CI/CD pipelines, you might want to create different results of the OpenAPI document. Having the option to rename them might make it easier to work with the results, so that is why we provide this command option.
$ openapi-format openapi.json -o openapi.json --rename "OpenAPI Petstore - OpenAPI 3.0"
which results in

🏗 BETA NOTICE: This feature is considered BETA since we are investigating the configuration syntax and extra formatting/casing capabilities.
openapi-format can help you to upgrade your current OpenAPI 3.0.x document to the latest version OpenAPI 3.1.
$ openapi-format openapi.json -o openapi-3.1.json --convertTo "3.1"
which results in all the changes described in the migration guide from Phil Sturgeon

All the CLI options can be managed in a separate configuration file and passed along the openapi-format command. This will make configuration easier, especially in CI/CD implementations where the configuration can be stored in version control systems.
example:
$ openapi-format openapi.json --configFile openapi-format-options.json
The formatting will happen based on all the options set in the openapi-format-options.json file. All the
available OpenAPI format options can be used in the
config file.
For handling AsyncAPI documents, we have created a separate package asyncapi-format to allow customisation specific for AsyncAPI use-cases.
We have adopted the YAML parsing style from Stoplight Studio, by leveraging the @stoplight/yaml package for handling the parsing of OpenAPI YAML files.
By using the Stoplight YAML parsing, the results will be slightly different from when using a normal YAML parsing library, like js-to-yaml. We appreciate the Stoplight Studio tool, since it is an excellent GUI for working with OpenAPI documents for non-OpenAPI experts who will be contributing changes. By adopting the Stoplight Studio YAML parsing, the potential risk of merge conflicts will be lowered, which is the main reason why we opted for using the @stoplight/yaml package.
This package is inspired by the @microsoft.azure/format-spec from @fearthecowboy. The original code was not available on GitHub, with the last update being 3 years ago, so to improve support and extend it we tried to reproduce the original functionality.
The filter capabilities from openapi-format are a light version grounded by the work from @MikeRalphson on
the openapi-filter package.
The casing options available in openapi-format are powered by the excellent case-anything nano package from Luca Ban (@mesqueeb).
