Are comments supported?

Lines starting with ; or # are treated as comments and ignored.

Can sections be nested?

Yes, use dotted section names like [server.db] to represent nested objects.

Are booleans and numbers detected?

Yes, values like true, false, and numeric strings are automatically typed.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
