Do I need a Chrome extension to format JSON?

No. FixTools works in any Chrome tab. Paste your JSON at fixtools.io and format it without installing any extension.

Why use FixTools over a Chrome JSON extension?

Chrome extensions require granting permissions and are installed permanently. FixTools runs as a website — open it when you need it, close the tab when done, with no persistent access to your browser.

Does FixTools format JSON that I view in Chrome?

If you navigate to a URL that returns raw JSON, Chrome may display it as plain text. Copy the JSON from the page and paste it into FixTools to format it.
