What is JSON Formatter?
JSON Formatter is a free online tool that formats, beautifies, minifies, and validates JSON data. Paste any raw or minified JSON and get it formatted with 2-space indentation. Also minifies JSON for production use.
How It Works
The tool uses JSON.parse() to validate and parse the input, then JSON.stringify() with indent parameter for formatting, or without for minification. Errors from JSON.parse are shown with the character position to help you find the issue.
