What information can you export from axe Developer Hub

Free Trial

axe Developer Hub is a beta product and is subject to change.

This article discusses how to export your accessibility issues from axe Developer Hub for use elsewhere. You can export your issues as either JSON or CSV.


From the issues page of axe Developer Hub, you can export your test run's issues in CSV or JSON format.

Export Examples

For the example export data in this article, there is one accessibility error in the source HTML: the web page was missing the lang attribute on the html element; it used <html> instead of <html lang="en">.

CSV Example

The first row of the CSV file indicates the column names.


Each column value is enclosed in quotes because some columns (such as Tags) can contain commas.

The Description, Rule Help, and Summary columns can contain HTML tags so their content needs to be escaped before including in a web page.

"Rule ID","Description","Rule Help","Help URL","Impact","Element Location","Element Source Code","Page State","Summary","Tags","Created At"
"html-has-lang","Ensures every HTML document has a lang attribute","<html> element must have a lang attribute","https://dequeuniversity.com/rules/axe/4.6/html-has-lang?application=axeAPI","serious","html","<html>","http://localhost:3000/index.html","Fix any of the following:
  The <html> element does not have a lang attribute","cat.language,wcag2a,wcag311,ACT","2023-03-20T17:43:17.204Z"

See Explanation of the CSV Columns and the JSON Properties below for information about the CSV columns.

JSON Example

For the same missing lang attribute, the exported JSON appears as follows:

    "id": "html-has-lang",
    "impact": "serious",
    "tags": [
    "description": "Ensures every HTML document has a lang attribute",
    "help": "<html> element must have a lang attribute",
    "helpUrl": "https://dequeuniversity.com/rules/axe/4.6/html-has-lang?application=axeAPI",
    "nodes": [
        "page_state": "http://localhost:3000/index.html",
        "created_at": "2023-03-20T17:43:17.204Z",
        "html": "<html>",
        "target": [
        "failureSummary": "Fix any of the following:\n  The <html> element does not have a lang attribute"

See the next section for information about the JSON properties in the export JSON.

Explanation of the CSV Columns and the JSON Properties

The following table explains the CSV columns and JSON properties. There are several embedded objects in the JSON:

  • tags, an array of strings representing each tag
  • nodes, an array of node objects
  • node, an object representing information about each accessibility error

For the table below, the node object and its contained properties are represented as node.property-name.
