FAQ

Does this validate my JSON?

Yes. If your JSON has syntax errors, the tool will highlight the error and show a red alert with the problem description.

Is there a size limit?

No formal limit, but very large JSON files (10MB+) may slow down your browser. For extremely large files, consider using a CLI tool.

Can I use this for API responses?

Absolutely. Paste raw API responses to format them for debugging. The formatted output makes nested structures much easier to read.
