About

JSON Formatter is a free, no-sign-up web tool. It formats, validates and minifies JSON and encodes or decodes Base64, with clear error messages that point to the problem.

Everything runs locally in your browser. What you type, paste or choose is never sent to a server, so there is nothing for us to store or leak. The site is supported by ads.
