Question 1

Can it handle large JSON?

Accepted Answer

It works within what the browser can handle. Extremely large JSON may take longer to format or validate and can make the page less responsive.

Can it format anything other than JSON?

Accepted Answer

This page supports only JSON formatting, minifying, and validation. YAML and XML are not supported here.

Not at this time. The tool uses a standard indentation setting. Custom indent widths are not supported.

Question 4

Can it handle JSON with comments (JSON5 or JSONC)?

Accepted Answer

This page supports standard JSON only. JSON5 and JSONC (with comments) are not supported.

Question 5

Can I copy the output directly?

Yes. You can copy the formatted or minified result with one click.

Question 6

How large a JSON file can it handle?
