Basic Usage

  1. Paste your JSON data into the Input JSON editor
  2. Select input format (JSON or JSONC with comments)
  3. Configure formatting options as needed
  4. Click Beautify to format your JSON
  5. The formatted result will appear in the Formatted JSON editor

Formatting Options

  • Sort Keys: Alphabetically sorts object properties for better organization
  • Minify: Removes all whitespace for compact, single-line output
  • Indent Spaces: Set the number of spaces used for each indentation level (0-10)

JSON Beautifier Features

  • Syntax Validation: Automatically checks for and highlights JSON syntax errors
  • JSONC Support: Handles JSON with comments (useful for configuration files)
  • Syntax Highlighting: Colors different parts of JSON for better readability
  • Copy Button: One-click copying of the formatted JSON
  • Maximize View: Expand the editor for working with larger JSON structures
  • Dark Mode Support: Comfortable editing in both light and dark environments
  • Multi-Format Export: Download formatted JSON as CSV, XML, YAML, or plain text

Helpful Tips

  • Use Sort Keys to make large JSON objects easier to navigate and read
  • Try Minify option when you need to reduce file size or prepare for production
  • Multi-Format Export: Download formatted JSON as CSV, XML, YAML, or plain text
  • Fix validation errors before proceeding - errors will be highlighted in red
  • Load the example JSON to see how the tool works if you're new to JSON formatting
  • For deeply nested structures, adjust indent spacing to improve readability

Export Options

The download feature allows you to convert and export your JSON data in multiple formats:

  • JSON (.json): Standard format for structured data exchange
  • CSV (.csv): Comma-separated values, ideal for spreadsheet applications
  • XML (.xml): Extensible Markup Language, widely used for data interchange
  • YAML (.yml): Human-readable data serialization standard, popular for configuration files
  • Text (.txt): Plain text format, universally compatible

Format Compatibility Tips:

  • CSV Export: Enable the Flatten option for best results with complex nested JSON structures. This creates a flat representation with dot notation that works well in CSV format.
  • XML Export: The Flatten option is not recommended for XML export, as XML requires hierarchical structure. You'll receive a warning if you attempt this combination.
  • YAML Export: Works well with both nested and flat structures, preserving the hierarchy of your data.

Note: When exporting to different formats, you may receive compatibility warnings depending on your JSON structure and selected options. These warnings will help you make appropriate choices for the best conversion results.

Privacy & Security: All JSON processing happens entirely in your browser. Your data isn't sent to any server, ensuring complete privacy and security for your sensitive information.
