FAQ

Is my JSON uploaded to a server?

No. Formatting runs entirely in your browser. Your data is not sent to our servers.

What indentation is used?

Choose 2-space or 4-space indentation in the input panel before formatting. The default is 2 spaces.

What does JSON Specification mean?

RFC 8259, RFC 7159, and ECMA-404 accept any JSON value. RFC 4627 requires a top-level object or array. Skip Validation uses the same parser but skips the RFC 4627 root-type rule.
