What delimiters are supported?

Comma (CSV), tab (TSV), pipe (|), semicolon (;), and a custom single-character delimiter you can enter yourself.

Does it handle quoted fields with commas inside?

Yes. CSV fields wrapped in double-quotes that contain the delimiter are parsed correctly and kept intact in the output.

What does the header separator option do?

It inserts a row of dashes after the first row, matching each column's width. This makes the first row look like a table header, similar to markdown tables.

Can I right-align numeric columns?

Yes. The right-align option pads spaces on the left so numbers line up on their right edge. Use it when your columns contain numeric data.

Is my data sent to any server?

No. All processing happens entirely in your browser. Your text never leaves your device.

What happens with empty fields?

Empty fields are preserved as blank cells, padded to match the column width so alignment is not disrupted.
