-- **Simple**: straightforward and flexible API
-- **Lightweight**: <2KB gzipped with everything included, <1KB gzipped when only using `json2csv`
+- **2 way**: convert JSON to CSV and the other way around.
+- **Simple**: straightforward and flexible API.
+- **Lightweight**: 2KB gzipped with everything included, 1KB gzipped when only using `json2csv`.
 - **Fast**: faster than the popular CSV libraries out there. See [benchmark](/benchmark).
-- **Modular**: only load what you use, thanks to ES5 modules and a plugin architecture
+- **Modular**: only load what you use, thanks to ES5 modules and a plugin architecture.
 - **Powerful**:
-  - Configurable properties: `header`, `delimiter`, `eol`
-  - Configurable `fields`, with custom value getters and setters and the ability to ignore fields
-  - Configurable serialization and deserialization of values via `formatValue` and `parseValue`
-  - Support for nested JSON objects: either flatten nested contents, or stringify as a JSON object
-- **Standards compliant**: adheres to the CSV standard [RFC 4180](https://datatracker.ietf.org/doc/html/rfc4180)
-- **Universal**: Created for the browser, but can be used in any JavaScript environment like node.js.
