Features

  • Format: Pretty print JSON with 2-space indentation.
  • Minify: Remove whitespace to save space.
  • BigInt Support: Safely handles large numbers that JavaScript's native JSON parser might corrupt.
  • Validation: instantly checks for syntax errors.

How it works

This tool uses json-bigint to parse and stringify JSON data, ensuring that numerical precision is maintained even for values larger than Number.MAX_SAFE_INTEGER.
