What is the JSON Formatter?

The free JSON Formatter and Minifier is a robust tool designed to help developers clean up messy, unformatted JSON strings. JSON (JavaScript Object Notation) is the standard format for data exchange on the web, but it often becomes unreadable when minified for production. Our tool instantly restores the proper indentation and structure to your data.

How to Use the JSON Formatter

  1. Paste your minified or unformatted JSON code into the input area.
  2. Click the 'Beautify / Format' button to add standard 2-space indentation.
  3. If you need to compress your data for production, use the 'Minify JSON' button to remove all whitespace.
  4. Copy the perfectly formatted result for use in your project.

Key Features

  • Instant Validation: Automatically checks for syntax errors in your JSON structure.
  • Premium Formatting: Uses standard 2-space indentation for maximum readability.
  • Minification Mode: Strip all whitespace to reduce file size for API responses.
  • 100% Client-Side: Your data is never sent to our servers; everything happens in your browser.
