JSON Lite

Fast JSON viewer - highlights, shows items count/size, handles large files

What is JSON Lite?
JSON Lite is a Chrome extension designed for fast and efficient JSON viewing. Capable of formatting JSON or JSONP responses and clipboard items, it offers readability features like collapsible arrays, objects, and values. Users can count items and properties in a collection, view collection sizes, and even manage large or invalid JSON files. The extension ensures the authenticity of numeric keys and large numbers by avoiding sorting or rounding. It also allows users to save the original JSON document and select/copy workable JSON from the formatted output.

Best JSON formatter for chrome.
by A Google user, 2018-12-02

I've been looking for this extension for a few years. I've used other JSON viewers/formatters and they've all been incredibly slow especially when hiding/revealing branches. I deal with large JSON datasets at my job and this plugin is easily the quickest of all that I have tried. Great job!
