Open and save Excel workbooks

Updated November 3, 2026

Cloud Sheets by MyCloudSuites opens the workbooks you already have and saves them so they open in Excel the way you left them.

Open a workbook

1. Choose File › Open.
2. Pick the file. Cloud Sheets opens:
   • Excel workbooks (.xlsx)
   • older Excel 97–2003 workbooks (.xls)
   • binary workbooks (.xlsb)
   • macro-enabled workbooks (.xlsm): the macros are kept, but never run
   • text files (.csv)

To start a new workbook, choose File › New.

Save it

Choose File › Save (Ctrl+S, or Cmd+S on a Mac). A workbook you opened is saved in its own format, so an .xls stays an .xls. A new workbook asks where to save it and in which format.

Anything Cloud Sheets doesn’t edit yet is kept as it was when you save, so it’s still there when someone opens the file in Excel.

Bring in a text file

To add data from a .csv or text file to a workbook, choose Data › From Text/CSV.

Save a PDF

Choose File › Export PDF to save the sheet as a PDF. To choose what goes on each page first, see Print a sheet or save it as a PDF.

If Cloud Sheets closes unexpectedly

While a workbook has unsaved changes, Cloud Sheets keeps a copy of it every few minutes. If the app ever closes unexpectedly, it offers that copy when you open it again.
