1. Paste JSON data
Paste or type your JSON data into the input field. Example:
{"name":"Test","value":42,"list":[1,2,3]}
2. Format or minify
- Format: Adds indentation and line breaks — makes JSON easy to read.
- Minify: Removes unnecessary spaces and line breaks — reduces data size.
- Clear: Clears both fields.
If the JSON data is invalid, the tool will display an error message with the location of the error.
3. Copy result
Press the Copy to clipboard button to copy the formatted or minified JSON for immediate use.
