Frequently Asked Questions
Is splitting CSV files with PDFPilot really free?
Yes. CSV Splitter is completely free to use, with no sign-up or account required.
Are my files uploaded to a server?
No. The splitting runs entirely in your browser. Your file is never uploaded to PDFPilot's servers.
Does every output file include the header row?
Yes — each split file repeats the original header row, so every part is a complete, valid CSV you can open on its own.
How are the output files downloaded?
As separate file downloads (split-part-1.csv, split-part-2.csv, and so on) triggered one after another, not as a single zip archive.
What if my file has a header but no data rows?
You'll get a clear error rather than an empty split — there's nothing to split if there's no data beneath the header.
