How to Use the JSON, XML, YAML Formatter & Minifier

Format Options:

  • Format:
    Choose the data type you want to format: JSON, XML, or YAML.
    Use “Auto-detect” to let the tool automatically recognize the input format.
  • Minify:
    Enable this option to remove all unnecessary spaces and line breaks, producing compact output.
    Leave it off for pretty-printed, human-readable formatting.

How to use:

  1. Paste or type your JSON, XML, or YAML data into the Input area.
  2. Select the correct format, or leave it as “Auto-detect” if you’re not sure.
  3. Optionally, enable Minify for compact output.
  4. The formatted or minified result will appear instantly in the Result area.
  5. Use the Copy button to copy your result, or Clear to reset and start over.

Tips:

  • The tool will highlight formatting errors if your input is not valid.
  • Pretty printing adds indentation and line breaks for easier reading and editing.
  • Minifying is useful for reducing file size or preparing data for production use.
