About this tool
Many apps limit how many rows you can import at once. Set the number of rows per file, and each part keeps the header so it is ready to import. Values with line breaks inside quotes stay in one piece.
How to use Split CSV
- Add a CSV file.
- Enter how many rows each file should hold.
- Select Split CSV, then download the parts together as a ZIP.
Frequently asked questions
Does the row count include the header?
No. With the header option on, each file holds your chosen number of data rows, plus the header.
Are cells with line breaks kept whole?
Yes. Rows are split by the CSV rules, so a line break inside a quoted value stays in that cell.
How large a CSV can I split?
There is no set limit. The file must fit in your device memory, so very large files work better on a computer.
