A tool better than Notepad++ for reading/writing jsons?
There are several json editing options, personally I use notepad++ but you could try visual studio code which is a free download. More on reddit.com

r/software on Reddit: I created a simple and free JSON editor
August 27, 2025 -

I’ve been working on a service API that deals with very large JSON payloads. My non-technical colleagues struggled to read or edit JSON directly, and most of the existing tools were either clunky, outdated, or ridiculously overpriced.

So I built Jsonite β€“ a lightweight, free JSON grid editor. Instead of working with raw JSON, you can view and edit documents in a clean spreadsheet-like editor with:

  • Keyboard shortcuts you’d expect (copy/paste, undo/redo, find/replace, etc.)

  • Instant editing with possibility to switch between grid/text view

  • Privacy by design since your data never leaves your browser and nothing is sent to a server

Although I originally made it to help my teammates, I soon found myself using it too, and I've been finding it pretty useful when dealing with large and complex data.

It’s completely free to use (both personal and commercial). Hopefully it can save you some headaches!
