JSON Formatter

Validate, Prettify, and Minify your JSON instantly.

Instant JSON Debugging

JSON (JavaScript Object Notation) is the language of modern APIs. However, raw JSON is often minified and unreadable for humans. This tool runs entirely in your browser (Client-Side), so your sensitive data never leaves your computer.

Features

  • Prettify: Indent and format JSON for readability.
  • Minify: Remove whitespace to reduce payload size for production.
  • Validate: Instantly catch syntax errors like missing commas or quotes.
