Questions about Log Formatter

Does this tool upload my input?

The conversion or analysis runs in your browser. The application does not intentionally send the value you enter to a processing API. Standard hosting infrastructure can still receive request metadata when the page loads; see the privacy page for details.

Can I rely on the output without checking it?

Use the result as a focused development aid and verify it in the system where it will be used. Test representative edge cases and confirm the destination uses the same format, standard, and assumptions described on this page.
