Any good App to edit .JSON files?
Any text editor should work because .json is basicly text file with different extention. Try to rename extension *.json to *.txt -> make editions as you like -> save then rename extension back to *.json Making backup of the original file is recomended though. PS: Or Edit on PC/MAC using one of these: Notepad++ (PC) Microsoft Visual Studio Code (PC) Sublime (Mac) More on reddit.com

April 15, 2024 -

Hey everyone,

I recently needed an app to browse a very large JSON file (>500MB) and could not find any open source app for Linux that could really do that. So I decided to make one myself and am now happy to share it with everybody, who might be interested.

The app is called Janice. It is written in Go and made with the awesome GUI toolkit called Fyne. It runs on Linux (AppImage), Windows 10/11 and macOS (experimental).

r/json on Reddit: Useful JSON viewer – JviewSON
January 25, 2025 -

Hey everyone!

I recently made a little tool called JviewSON, and I thought it might come in handy for anyone who works with JSON files regularly. It’s simple and designed for viewing and analyzing JSON files without any unnecessary extras.

A few key features:

  • Displays JSON data in a clean and easy-to-read structure.

  • Built-in search to help you find what you need fast.

  • Automatically updates if the JSON file changes in the background.

  • It’s view-only, so no risk of accidentally editing your data.

If you’re curious, you can check it out on itch.io, where you can also run a browser-based version without downloading:
https://pocdev.itch.io/jviewson

Or if you prefer to dig into the code (made in Godot) here’s the GitHub repo:
https://github.com/andreas-volz/JviewSON

Would love to hear what you think or if you have any ideas for improvement!
