r/webdev on Reddit: Chrome extension JSON viewer
February 19, 2024 -

In case anyone else is needing a way to view large JSON files (10MB+), I wrote this extension for Chrome:

https://chromewebstore.google.com/detail/json-navigator/glgilclfmgofaeffphalkglkgbbpmigf

It loads large JSON files faster than Chrome can generate the preformatted text (by a long shot), and has a lot of useful features that make finding the needles in the haystack easier.

Enjoy :)
