I had trouble with other JSON viewers after migrating from firefox to brave. Still, thanks to this extension, I could view JSON data exactly like firefox.

Simply the BEST JSON Viewer ever. It has everything I wanted. light and dark theme, expand all, collapse all, search box, SAVE, COPY, headers, raw data! The last thing I would request to add is a jJSON data "address" indicator that would show how I'm gonna access a selected line in a JSON file. Thank you for creating this extension.

Tried other viewers on chrome and nothing comes any close to this one. Was missing Firefox's JSON viewer whenever I used chrome and this extension bridged the gap! Thanks Rongjian!

This is exactly what I was looking for. Firefox has their own JSON viewer. It is exactly that but for Chrome. Tried some other viewers but none was like it. Here is the Github link for this project if you want to look at - https://github.com/pd4d10/json-viewer . This is greatly done and UI is good too. At last found something reliable. Thanks guys, keep it up.
