About Split CSV
Two ways to split
- By row count — "every 1000 rows is a new file". Useful when something can't ingest your full file (e.g. a tool with a 10k-row limit).
- By column value — one file per distinct value in a column you pick. Useful for splitting
orders.csvinto one file percountry, ortickets.csvinto one file perassignee.
The header row is duplicated into every output file by default, so each part is valid on its own. You can switch this off if you'd prefer raw chunks.
What you get back
A single ZIP containing every part. Files are named so they sort correctly: users_part001.csv, users_part002.csv, … or users_country_USA.csv, users_country_UK.csv, etc.
Frequently asked questions
No. Splitting and zipping happen entirely in your browser using PapaParse and JSZip.
Check the rows-per-file value or the column you picked. If a column has only one distinct value, splitting by it produces one file.
The split itself is fast for any size, but the ZIP is held in browser memory before download. Files up to ~200 MB usually work; bigger workloads may need a desktop tool.
