Frequently Asked Questions

Can this tool fix my invalid JSON automatically?

While our tool identifies errors like missing quotes or extra commas, it does not automatically "guess" how to fix them to prevent data corruption. However, the error messages provided will tell you exactly which line to look at.

Is there a limit to the JSON file size?

The limit depends purely on your browser's memory. Our tool can easily handle JSON files up to several megabytes without any lag.
