Chrome JSON Viewer and Formatter

The JSON Formatter Hub Chrome extension helps you inspect JSON directly while browsing. It is useful when you open API endpoints, JSON files, or raw responses and want a readable tree view, search, formatting, and quick access to the full JSON Formatter Hub toolset.

Install JSON Formatter Hub for Chrome from the Chrome Web Store.

Open Chrome Web Store

What the Extension Helps With

Chrome JSON viewer: inspect raw JSON responses in a readable format.
JSON tree view: expand and collapse nested objects and arrays.
Search JSON: find keys and values inside large responses.
Quick formatting workflow: move from a browser response to the full JSON Formatter Hub tool when needed.

When to Use the Website Instead

Use the website when you need advanced actions such as Auto-fix, Remove Whitespace, Compare JSON, or Export/Download as JSON, CSV, YAML, or XML. Use the extension when you want a faster browsing workflow for API endpoints and JSON pages.

Best Fit

The extension is designed for developers, QA engineers, API testers, and students who frequently open JSON in Chrome. It complements the main online JSON formatter rather than replacing it.
