Frequently Asked Questions

How does the CSV batch splitter work?

Choose one or more CSV files, pick how many rows you want in each batch or enable smart auto split, then click the split button. You will receive a single ZIP file containing all generated CSV batches.

What does smart auto split do?

Auto split reads your CSV size and suggests a batch size that balances performance and file count. Smaller files get smaller batches, very large files get larger batch sizes to avoid hundreds of tiny files.

Will the header row be included in every split file?

Yes. Each batch keeps the original header row so that every split CSV can be used independently in tools like Excel, Shopify, Amazon or ERP imports.

Do you remove empty rows or duplicates?

The preview shows how many empty and duplicate rows exist so you can decide whether to clean the source file first. The splitter keeps the data as it is and does not automatically remove any rows.

Is this CSV splitter free and secure?

Yes, it is free to use. Files are processed on the server only for the duration of the split process and temporary files are deleted right after the ZIP is generated.
