Question 1

Does this tool fix invalid JSON automatically?

Accepted Answer

No. It reports syntax errors with line and column numbers so you can fix them manually. This prevents silently corrupting your data.

Question 2

Is there a file size limit?

Accepted Answer

There is no hard limit, but very large files (10MB+) may slow your browser. For huge payloads, consider a CLI tool like jq.

Question 3

Can I format JSON with comments?

Accepted Answer

Standard JSON does not support comments. JSONC (JSON with comments) is not supported — strip comments before formatting.

Question 4

Is my JSON data stored anywhere?

Accepted Answer

No. All processing happens in your browser. Zovaty never receives or stores your JSON.
