Split a large CSV for an upload limit

The import screen says 10,000 rows or 10 MB per file. Cutting by hand loses the header or breaks a row halfway. Splitting by row count or size is safe.

Open Split CSV

Steps

  1. Drop the large CSV on "Split CSV". Its row count and size are shown.
  2. Choose how to split: "10,000 rows per file" or "under 10 MB".
  3. Each part carries the header row, and no row is ever cut in the middle.
  4. Save them together (ZIP) and upload them in order.

Questions

Are line breaks inside a cell handled?
Yes. A quoted line break stays inside its row, so a row is never cut in two.
Is the data uploaded?
No. The split happens in your browser; press "Network" in the bar to see for yourself.

The CSV is never sent anywhere; everything runs in this browser.
