JSON formatter

Beautify and format your JSON data to make its structure clear and easy to read.100% local processing, zero upload, zero risk.

What does JSON formatting do?
JSON formatting makes raw JSON data easier to read and edit. By adding appropriate indentation, line breaks, and spacing, it makes the JSON structure more clearly visible.
How does this tool validate JSON?
The tool validates the JSON syntax during the formatting process. If the JSON contains syntax errors, the tool will display an error message to help you locate and fix the issue.
Are there issues with large JSON files?
This tool uses in-browser processing and works well with medium-sized JSON files. For very large files (several MB or more), there may be some performance impact.
What's the difference between formatted and original JSON?
There is no difference in data content; formatting does not change the JSON data structure or values. The only change is the distribution of whitespace characters (spaces, tabs, line breaks) to make it more readable.
