A Chrome browser extension that formats and pretty-prints JSON API responses with syntax highlighting, collapsible trees, dark mode, and console access to parsed data. The open-source project is archived, with a final 'JSON Formatter Classic' version available for use or fork.

- inspect json in devtools console
- view large json files fast
When to choose

When to avoid
- you need ongoing updates or support - the project is archived
- you want a comprehensive API-browsing tool with premium features
