About JSON Formatter

Our JSON Formatter tool helps you beautify, minify, and validate JSON data with proper syntax highlighting. It's perfect for developers who need to work with JSON data regularly.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language and has become the standard format for data exchange in web applications.

JSON is built on two structures:

  • A collection of name/value pairs (similar to objects in JavaScript)
  • An ordered list of values (similar to arrays in JavaScript)

Features of Our JSON Formatter

  • Minify JSON - Remove all unnecessary whitespace to reduce file size for production
  • Validate JSON - Check if your JSON is valid and see detailed error messages if it's not
  • Syntax Highlighting - Different colors for keys, values, and punctuation make JSON easier to read
  • Copy to Clipboard - Easily copy the formatted JSON with one click
  • Download as File - Save the formatted JSON to your device
  • Drag and Drop - Simply drag and drop your JSON files for quick formatting
  • Keyboard Shortcuts - Use keyboard shortcuts for faster workflow
