Frequently Asked Questions
What happens if my JSON has syntax errors?
The formatter pinpoints the exact line and position where the syntax error occurs (such as trailing commas or missing quotes).
Is there a size limit for formatting?
Because processing happens directly in your browser's V8 engine, you can format multi-megabyte JSON files instantly without uploading.
