  • Prepare JSON for configuration files.
  • Minify JSON before storing or sending it.

Examples

Object formatting

{"ok":true,"items":[1,2]}
{
  "ok": true,
  "items": [
    1,
    2
  ]
}

FAQ

Does this change the data?

No. Formatting changes whitespace only; compact mode removes unnecessary whitespace.

Can it validate JSON?

Yes. Invalid input returns a clear parsing error instead of partial output.
