JSON Editor

A tool to view, edit, format, and validate JSON

JSON Editor: Powerful JSON Viewing and Editing Tool

JSON Editor is an intuitive Chrome extension designed for developers and data professionals who need an efficient way to view, edit, format, and validate JSON data. It features a side-by-side treeview and code editor which makes inspecting and modifying JSON both visual and straightforward.

With JSON Editor, you can easily add, move, edit, or remove fields and values, change value types, and sort arrays or objects. The editor applies color coding based on value types for quick identification, supports search and highlight within the treeview, and provides undo and redo functionality for seamless editing. Additionally, it allows loading and saving JSON files from disk, cloud services, or URLs. You can also validate your JSON against JSON schemas and format or compact your JSON data in the code editor for better readability or storage optimization.

Experience a powerful and user-friendly JSON editing workflow right in your browser with JSON Editor!

User reviews

Users appreciate JSON Editor for its fast performance, intuitive tree structure visualization, and ease of use, especially with large JSON files. It is lightweight and reliable for daily tasks. However, there are common issues including lack of support after December 2022, problems saving files, difficulties with inputting non-English characters (notably Chinese and Korean), occasional crashes on Mac OS, and reported slowdowns within Chrome that disappear when the extension is disabled.
Pros
  • Supports JSON formatting and structure management with a convenient tree visualization.
  • Fast and efficient even with large JSON files (e.g., 50MB open in ~2 seconds).
  • Lightweight, simple, easy to use, and reliable for daily use.
  • Useful features like offline validation and independent window opening.
  • Good layout and overall great user experience praised by many users.
Cons
  • No support or updates as the old version is deprecated (post-December 2022).
  • Issues with saving JSON files to disk—save button not functioning for some users.
  • Input problems with non-English characters, especially Chinese and Korean input errors.
  • Crashes or fails to open properly on Mac OS when using shortcuts or as a standalone app.
  • Some users report slowdowns and delays in Chrome associated with the extension, resolved after disabling it.
