About

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.

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