What to know

Columns are matched by name, ignoring case, not by position.

Without a header row, files are simply stacked, so make sure their columns line up.

File handling: This tool runs in your browser. Your text or file is processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
