In code review

Our reviewer read this extension’s code and found no malicious behaviour. An automated risk flag was reviewed and overturned.

What our analysis found

JSON Formatter, used by 2,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a trusted publisher and was last updated in May 2026.

The extension only formats JSON in the current page and stores a theme preference locally. No network requests, no data collection, no remote code. Broad host permissions are necessary for its stated purpose. The ML model likely flagged it due to minified code patterns and high appendChild counts from DOM construction, not actual malicious behavior.

About this extension

Makes JSON easy to read. Open source.

Read the publisher’s full description

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.
