CSV Splitter
Split a large CSV into smaller chunks.
Break a big CSV into parts
Some tools cap import size. This splits a large CSV into chunks of the row count you choose, repeating the header on each chunk so every piece is a valid file on its own.
It is the answer to an import that rejects a file for being too big, or to sharing a manageable slice of a large dataset without sending the whole thing.
Header on every chunk
That means each part imports cleanly without manual fixing. The split runs in your browser and nothing is uploaded. Your file is split on your device and never uploaded.
