About JSON Formatter
Makes JSON easy to read
The original JSON Formatter, now with optional dark mode 🌚
Auto-formats JSON when you load it in a browser tab.
FEATURES
- Fast, even on very long JSON pages - Dark mode - Syntax highlighting - Collapsible trees, with indent guides - Clickable URLs - Negligible performance impact on non-JSON pages (less than 1 millisecond) - Works on any valid JSON page – URL doesn't matter - Buttons for toggling between raw and parsed JSON - FIXED: Exports the parsed JSON to window.json so you can explore it in Dev Tools
Note: this extension might clash with other browser extensions that modify the DOM before it runs. If it doesn't seem to be working, try disabling other extensions. If it clashes with an extension you need, open an issue and I'll try to find a solution.
SOME EXAMPLE JSON PAGES to try it out on: https://callumlocke.github.io/json-formatter/
PRO TIP Hold down control (or cmd on Mac) while collapsing a tree - collapses all siblings too.
PRIVACY No tracking, no advertising, and nothing else nefarious.

Data source
User counts are read from public Chrome Web Store listing pages. Google displays rounded user counts (and caps the display at 10,000,000+), so small changes may not be visible. Rating counts above 1,000 are rounded (e.g. 1.6K).
