This is a port of Firefox's JSON Viewer

If you open a JSON file in the browser, it is parsed and given syntax highlighting. Arrays and objects are shown collapsed, and you can expand them using the "+" icons.

The single best json viewer extension. Works on huge payloads and on streamed responses.

Peter Mckenna 2025-05-21

When it works it is very nice. However it doesn't always work reliably. I've just opened a clearly JSON formatted file ending with .json in the browser's regular window and it has not been picked up by this extension. It's happened a few times recently.

Works beautifully

Me encantó, siempre busqué algo que me mostrase los archivos JSON. Absolutely lovely! I was looking for an extensions that shows JSON natively as chrome network tab, unfortunately there's no one, but this is amazing!!

Does not work anymore for me as well.

Suddenly degraded. Only "pretty print" function is shown in UI, but others are not.

Just what we needed!!!

Works now in Chrome 117, updating review to 5 stars!

was nice until one of the latest chrome updates broke pretty much all json viewer extensions somehow

Does what it says on the tin - when you visit a file, or JSON response it displays a useful JSON debugging UI that's easy to work with.

This exactly what am i looking for as well. Been so used to the beauty of Firefox json viewer and so happy to see someone had made the effort to port it over to Chrome. Love XXXXXX

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.

It's very useful.. i finally found a nice JSON viewer like in Firefox

Jeryl Estopace 2020-04-11

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.

很棒,火狐的这个还是美观啊

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.
