OFFICE✂️Split CSV

By rows/count/column · ZIP bundle

📦100% browser-local· processing in browser, no upload

Multiple files are auto-packed into a ZIP; a single file downloads as CSV directly.

Split CSV: By Rows / Shares / Column Value

Typical scenarios: ① split a large file into smaller ones for batch import; ② distribute data to different teams by customer or region; ③ archive data by a column value such as month.

How to use: upload a CSV and choose how to split — by row count, by number of parts, or by the values of a column. The tool packages the result into multiple small files, each with a header.

Notes: ① before splitting by column value, sort by that column so rows with the same value don't scatter across files; ② every split file keeps the header and can be opened on its own; ③ splitting is irreversible — keep the original file before you start.
