Convert axe-core accessibility scan results to the SARIF format

Version published




Build status Code coverage npm semantic-release

Convert axe-core accessibility scan results to the SARIF format. Provides both a TypeScript API and a CLI tool.

Use this with the Sarif Viewer Build Tab Azure DevOps Extension to visualize accessibility scan results in the build results of an Azure Pipelines build.


Before using axe-sarif-converter, you will need to run an axe accessibility scan to produce some axe results to convert. Typically, you would do this by using an axe integration library for your favorite browser automation tool (@axe-core/puppeteer, @axe-core/webdriverjs, cypress-axe).

axe-sarif-converter exports a single function, named convertAxeToSarif. Use it like this:

import * as Axe from 'axe-core';
import * as AxePuppeteer from '@axe-core/puppeteer';
import * as fs from 'fs';
import * as Puppeteer from 'puppeteer';
import * as util from 'util';

import { convertAxeToSarif, SarifLog } from 'axe-sarif-converter';

test('my accessibility test', async () => {
    // This example uses @axe-core/puppeteer, but you can use any axe-based
    // library that outputs axe scan results in the default axe output format
    const testPage: Puppeteer.Page = /* ... set up your test page ... */;
    const axeResults: Axe.AxeResults = await new AxePuppeteer(testPage).analyze();

    // Perform the conversion
    const sarifResults: SarifLog = convertAxeToSarif(axeResults);

    // Output a SARIF file, perhaps for use with a Sarif Viewer tool
    await util.promisify(fs.writeFile)(
        { encoding: 'utf8' });

You can also use axe-sarif-converter as a command line tool:

# @axe-core/cli is used here for example purposes only; you could also run axe-core
# using your library of choice and JSON.stringify the results.
npx @axe-core/cli --save ./sample-axe-results.json

npx axe-sarif-converter --input-files ./sample-axe-results.json --output-file ./sample-axe-results.sarif

See npx axe-sarif-converter --help for full command line option details.


The microsoft/axe-pipelines-samples project contains full sample code that walks you through integrating this library into your project, from writing a test to seeing results in Azure Pipelines.

Version numbers

The version number of this library is independent from the version numbers of the axe-core inputs and SARIF outputs it supports.

  • axe-sarif-converter version 2.x supports input from version ^3.2.0 || ^4.0.0 of axe-core (tested with 3.2.2, 3.3.2, 3.4.1, 3.4.2, 3.5.1, 3.5.2, 3.5.3, 3.5.4, 3.5.5, 4.0.1, 4.0.2, 4.1.1, 4.2.0, 4.3.2, 4.4.1, and 4.6.3) and outputs SARIF v2.1
  • axe-sarif-converter version 1.x supports input from version >= 3.2.0 < 3.3.0 of axe-core (tested with 3.2.2) and outputs SARIF v2.0

Note that the SARIF format does not use semantic versioning, and there are breaking changes between the v2.0 and v2.1 SARIF formats. If you need compatibility with a SARIF viewer that only supports v2.0, you should use version 1.x of this library.
