JSON formatter, validator, and minifier
Validate JSON with clear errors, format it for reading, or minify it locally.
How it works
Validate JSON with clear errors, format it for reading, or minify it locally. Review the displayed limits, choose your input, and run the operation. Browser tools keep data on this device. Server tools use private generated paths, isolated workers, verified outputs, and automatic deletion. Unsupported, malformed, or oversized inputs fail with a stable error without exposing their contents.
