Is cleaning CSV files with PDFPilot really free?
Yes. CSV Cleaner is completely free to use, with no sign-up or account required.
Are my files uploaded to a server?
No. The cleaning runs entirely in your browser. Your file is never uploaded to PDFPilot's servers.
What exactly counts as an "empty row"?
A row where every cell is empty after trimming whitespace — a row with even one non-blank cell is kept.
Does this remove duplicate rows?
No — this tool only handles whitespace and empty rows. Use Duplicate Row Remover separately for exact duplicate rows.
Is the header row treated specially?
No — it's cleaned the same way as every other row (whitespace trimmed), but it's never dropped even if unusual, since it's still a real, non-empty row.
