FAQ

How do I split a CSV file into multiple files?
The simplest approach is to choose a row limit for each output file, preserve the header row, and generate multiple smaller CSV parts from the original dataset.
Will the split files keep the header row?
Good CSV split workflows usually preserve the header row in every file so each part can still be used independently.
Why would I split a CSV instead of keeping one big file?
Smaller files are usually easier to upload, share, open in spreadsheets, and process in batches without hitting size or memory limits.
