JSON beautify, minify, and schema check

Pretty-print JSON for readability, minify for compact payloads, validate syntax, or check documents against a JSON Schema. Handy for APIs, config files, and structured data drafts before you publish them on a site.

Useful workflows

  • Clean API responses while debugging integrations
  • Validate CMS export files before import
  • Sanity-check JSON-LD samples alongside the schema validator

Best practices

Keep schemas versioned, reject unknown critical fields in production APIs, and never paste secrets into public tools on shared computers.
