How the Excel hub works

One workbook powers multiple Excel utilities in the same session.

  1. Upload a workbook once.
  2. Switch tabs to convert, clean, extract columns, merge sheets, or find duplicates.
  3. Download the result you need without re-uploading the same file.

Planned Excel tools

The hub can absorb more tools without changing the upload flow.
