Browser extension that changes the way you're viewing JSON

What is JsonDiscovery?
JsonDiscovery is a Firefox add-on that enhances the way you view JSON. It replaces the default Firefox JSON viewer with an interactive tree view, allowing easy copying, data transformation, customization, and more. It works on any page with valid JSON, including local files, without requiring any network requests.

IMPORTANT! To make JsonDiscovery working, you should disable the default Firefox's JSON viewer:

  • Navigate to "about:config"
  • In search field type 'devtools.jsonview.enabled'
  • Toggle this setting to false

Most exciting features:

  • Show JSON as an interactive tree with highlighting
  • Easy an object or an array copy to clipboard
  • Data structure signature (like in TypeScript)
  • Data transformation with a query using Jora, suggestions on a query typing
  • Customisation of JSON data presentation (using tables, lists and so on)
  • Customisation (report) sharing by a link
  • Works on any page with a valid JSON – URL/content type doesn't matter
  • Works on local files
  • Works offline (doesn't perform any network request)

Best json extension on Firefox! Only one thing missing, and that is the ability to make the font larger appwise.
