Excel (XLSX) to PDF Converter

Defaults to Landscape, not Portrait - spreadsheets are usually wider than they are tall, and this alone is normally enough to stop columns getting cut off. Paper size defaults to Auto, which counts your sheet's actual columns and switches to the wider A3 automatically once there are enough of them that A4 likely won't fit them all - force a specific size below if you'd rather choose yourself. "Fit to page width" is applied too as an extra safety net, but landscape/paper size is what this actually depends on: shrink-to-fit can be unreliable for PDF export in the underlying library, so it isn't the only thing holding this up. Column headers also repeat on every page automatically for sheets long enough to span more than one.
