About JSON Formatter
The JSON Formatter is a client-side tool that takes unformatted or minified JSON data and formats it with proper indentation, spacing, and line breaks. It's an essential tool for developers who frequently work with API responses, configuration files, and data transfer objects.
How to use
  1. Paste your raw JSON data into the input field on the left.
  2. Select your preferred indentation style (2 spaces, 4 spaces, or tabs).
  3. Click the "Format" button to process your data.
  4. If your JSON is valid, the formatted output will appear on the right side. You can quickly copy it using the copy icon.
  5. If your JSON contains syntax errors, a descriptive error message will be shown to help you locate the issue.
Privacy FirstThis tool operates entirely within your browser. Your JSON data formatting is performed locally and is never sent to our servers or stored anywhere.
