One workbook per customer, state, rep, department — you pick the column, we do the cutting. Header row kept or dropped, XLSX or CSV out, everything zipped. Or convert the whole file XLSX ⇄ CSV.
You have one giant spreadsheet and N people, systems, or clients who each need only their slice. Stop copy-pasting rows into new workbooks by hand.
Customer, state, sales rep, department — any column, A to AZ. The dropdown shows each one with its header name, and the preview tells you exactly how many files you'll get.
All rows for ACME go to ACME.xlsx, all rows for Globex to Globex.xlsx — sorted or not. Prefer a new file each time the value changes? There's a mode for that too.
Header row in every file (or not — your call), XLSX or CSV, all bundled. Fifty files, one download, zero uploads.
Same rules as the rest of this site: parsing happens in your browser, nothing is uploaded, nothing is stored, no account. Load the page, go offline, keep splitting — it still works. Customer lists, payroll data, PII of any flavor: there is no server for it to reach.
Drop your file, pick the column, download the ZIP. Every value in that column becomes its own file with the header row on top.
Yes — the dropdown lists every column as A, B, C… with its header name, and the preview updates as you switch. Column A is just the default.
No. There is no upload, no server, no storage. It even works offline once the page has loaded.
Yes — "one file per distinct value" gathers every row with the same value no matter the order. Use on-change mode only when your data is sorted and you want consecutive runs.
By default yes. Uncheck the option for data-rows-only files, for imports into systems that add their own headers.
Yes — choose "Convert the whole file" for XLSX→CSV or CSV→XLSX. Split mode also outputs either format.
