How to use Split Excel
- Select an Excel or CSV file.
- Choose split by sheet or by row count.
- Download the pieces (multiple files arrive as a zip).
Is it private?
Yes. Split Excel runs 100% inside your web browser. Your files are never uploaded to a server, so even we can’t see them. That makes it a safe choice for sensitive spreadsheets, contracts, and personal documents.
Frequently asked questions
Does each chunk keep the header row?
Yes — when splitting by row count, the header is repeated on every output file.
Is my data uploaded?
No, everything happens on your device.
