About Split CSV by Row Count
Split local CSV data into up to 1,000 files, repeat headers in each part, and download every batch inside one ZIP.
CSV Split divides parsed data rows into numbered CSV files and packages them in one ZIP. When headers are enabled, the original header is repeated in every part without counting toward the requested row limit.
How to use it
- Paste or load the source CSV.
- Choose delimiter, header behavior, and data rows per file.
- Create and download the ZIP of numbered parts.
Common use cases
- Create import batches that respect a row limit.
- Divide a large export for review by several people.
- Produce smaller CSV attachments from one source file.
Worked example
Split a 12,350-row export into thirteen files with at most 1,000 data rows each.
Limitations and responsible use
- Rows remain in source order and are not balanced by category or field value.
- The operation can create at most 1,000 files per run.
- Every row must match the parsed column count before splitting.
Frequently asked questions
Does the header count as a data row?
No. With headers enabled, each part receives the header plus the requested number of data rows.
What happens to the final incomplete batch?
It is included as the last CSV file with its remaining rows.
