Add-on summary

Open web pages with JSON content or JSON files to view, edit, format, repair, query, transform, and validate JSON directly on the browser.

Features:

  • View JSON as a tree. The JSON tree view utilizes right-click to open the context menu, and double-click to start editing a key or value. It supports copy/paste from and to the system clipboard.
  • View JSON as formatted text.
  • View JSON as a table, for top-level arrays or nested arrays.
  • Search and replace
  • Undo and redo actions
  • Edit the JSON keys, and values, copy, paste, duplicate, insert, or remove
  • JSON formatting and minifying
  • Query JSON with plain JavaScript or using the built-in form
  • Sort, filter, and transform JSON
  • Handle large JSON documents up to 512 MB

It uses the powerful https://github.com/josdejong/svelte-jsoneditor/ and the Manifest V3 for enhanced security, privacy, and performance.

It couldn't even be opened or open a JSON file with it.

Great UI of this addon, but can't find a way to save Key or Value entries using firefox v.123 - no Save menu-option shows, and ctrl/s saves the json file but without additions or changes to any values?!
