Split full names, addresses or codes into several columns, or join columns into one with any separator.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Split & Combine Columns works

Files are opened in your browser with SheetJS and JSZip. Nothing is uploaded, and your original file is never changed. Split at a separator, by fixed widths, a full name into first, middle and last, or an email into user and domain.

Input: XLSX, XLS, ODS, CSV. Output: XLSX, CSV.

How to use Split & Combine Columns

  1. Drop a spreadsheet.
  2. Choose split or combine.
  3. Pick the columns and options.
  4. Download.

Tips

  • Excel, ODS and CSV all work. Formulas are read as their last saved values.
  • For CSV files with odd characters, save them as UTF-8 first.

Split & Combine Columns FAQ

Are my files uploaded?
No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
Is it free? Are there limits or watermarks?
Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
Does it work offline?
Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
