Installation

Usage

Open web pages with JSON content or JSON files 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

Make sure to disable any other JSON viewing built-in into the browser or other browser extension JSON viewer/editors.

Why is the access to all URL sites needed?

To render the JSON Editor UI on any web pages with JSON content or JSON files opened with the browser, the content script execution needs to happen on all URLs.

What data do you collect?

JSON Editor does not collect or store any of your data, or track your usage in any way, and will never do so.

Check the full JSON Editor's privacy policy.
