What is JSON Formatter?

JSON is a portable text data format for APIs and configuration. Formatting adds indentation for humans; minifying removes unnecessary whitespace without changing the parsed data.

  1. Paste JSON into the input field.
  2. Select Format or Minify and run the transformation.
  3. Review validation feedback and copy the result.

Example
