Does it show where JSON is invalid?

Yes - validation errors include the parser message, which pinpoints the offending position.

What indentation options exist?

Two spaces (default), four spaces, or tabs for minified-free pretty printing; one-click minify for compact output.

Is my data sent anywhere?

No. Formatting runs in your browser tab - safe for secrets, tokens, and production payloads.
