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 a row count is safe.

Open “Split a CSV”

Steps

  1. Drop the large CSV on "Split a CSV". Its row count is shown. Up to 50,000 rows is free; a longer file needs the Pass.
  2. Press the preset "Every 10,000 rows", or type a number in "Rows per file". For a size limit (10 MB, say), choose fewer rows.
  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.
How large can the CSV be?
Up to 50,000 rows for free. A longer file needs the Pass. Every file can be up to 200 MB.
Is the data uploaded?
No. The split happens in your browser. The "Network" chip in the bar lists the connections this page can see (connections from background workers, WebSocket and WebRTC are not on that list; this site works in a background worker). What goes out is set out at https://orihako.com/trust/.

The CSV is never uploaded; everything runs in this browser.
