JSON Formatter & Validator
Format, beautify, minify, and validate JSON data with our enterprise-grade editor. Compare differences side-by-side.
How It Works
Paste Your JSON
Paste your JSON data into the input editor on the left. The editor supports syntax highlighting and auto-validation.
Format or Minify
Click "Format" to beautify your JSON with proper indentation, or "Minify" to compress it for efficient storage.
Copy & Compare
Copy the formatted result to your clipboard. Use "Diff" mode to compare two JSON documents side-by-side.
JSON formatter FAQs
Is my JSON data stored when I use this tool?
Your JSON is processed for validation and formatting as part of your session. It is not intended to be stored long term, but as a security best practice you should avoid pasting highly sensitive secrets, tokens, or credentials into any online formatter.
Does the formatter change the meaning of my JSON?
Formatting and minifying only affect whitespace and layout. The underlying key-value pairs and array structure remain the same. Always review the result before using it in production or committing it to version control.
Why is diff mode useful?
Diff mode lets you compare two JSON payloads side by side in the Monaco editor, which is helpful for debugging API responses, config changes, or investigating production issues.
