What is JSON Validation?

JSON (JavaScript Object Notation) is a lightweight data-interchange format widely used for APIs and configuration files. This tool helps you validate your JSON for syntax errors, format it for readability, or minify it for compact storage.

  • Paste or type your JSON and click Validate & Format to check for errors and beautify the output.
  • Use Minify to compress your JSON for use in production or network transfer.
  • All processing happens in your browser—your data never leaves your device.
