About CSV Splitter
The CSV Splitter divides a large CSV file into multiple smaller files, each containing a specified number of rows. Every chunk automatically includes the original header row, so each part is a standalone, valid CSV file.
Common Use Cases
- Uploading large CSV files to services that have row-count limits (e.g. email marketing platforms, CRMs).
- Processing large datasets in batches in your scripts or pipelines.
- Sharing subsets of data with team members without sending the entire file.
