Question 1

How do I split a large CSV file into smaller parts?

Accepted Answer

Upload your CSV and choose to split by row count (e.g., 5,000 rows per file) or by number of equal parts. Headers are automatically included in each output file. Download all parts as a ZIP archive.

Question 2

Why do I need to split my CSV file?

Accepted Answer

Google Sheets has a 10 million cell limit, and many tools have row count limits. Splitting lets you work with large datasets across multiple files or sheets. It's also useful for batch processing or emailing files within size limits.

Question 3

Are headers included in each split file?

Accepted Answer

Yes. The first row (headers) is automatically copied to the top of each split file, so every part is a valid, self-contained CSV that can be opened independently.

Question 4

What's the maximum file size I can split?

Accepted Answer

Since processing happens in your browser, the limit depends on your device's memory. Files up to a few hundred megabytes typically split without issues. The tool processes data in chunks to minimize memory usage.
