Overview
Product summary
Review the store description, core capabilities, and common use cases.
This extension monitors JSON pages and converts them into a human-readable object. You can view, edit, search through values and keys. You can even change the format of a key or drag it into a new place. There is no need to do anything after installation. Just open a JSON page and the extension automatically converts the page into the editor mode.
As of version 0.2.0, the extension uses a dark theme if your browser's default theme is dark.

one of the best.
Love the way it formats, sorts and present the JSONs. A must have for all developers! #QualityOfLife+
This is really good. Clean layout and different viewing options are great.
Way better than any other JSON beautifiers I tried! Fully recommended!
Simplemente genial.
no settings option , ugly theme and not as neat as firefox json viewer, but rating 5 stars because this is better than the other json extensions by far
Works very well, the jmespath implementation is super useful for frontend developers
Best of all
This is perfect!
Very good extension, please add an option to auto expand all nodes, that would make it perfect.
