What delimiter does the parser support?

The tool auto-detects commas (,), semicolons (;), and tabs as delimiters. It picks whichever appears most frequently in the first line.

How are data types inferred?

Integer strings (e.g. 42) become TOML integers, decimal numbers (e.g. 3.14) become floats, "true"/"false" (case-insensitive) become booleans, and everything else becomes a quoted string.

Are quoted CSV fields supported?

Yes. Fields wrapped in double quotes are parsed correctly, including values that contain the delimiter or newlines within quotes.

Is my data sent to a server?

No. All parsing and conversion happens entirely in your browser using JavaScript. Nothing is uploaded or stored.

What happens with empty cells?

Empty cells are output as empty strings ("") in the TOML output. You can clean them up manually if needed.
