Word UserForm, Excel UserForm, they're both the same.

If you have to run from Word, you'll need to use Automation to talk to
Excel, something like ..

   Set xlApp = CreateObject("Excel.Application")
   Set xlBook = xlapp.Workbooks.Add
   Set xlSheet = xlwb.Sheets(1)

You can then reference individual cells like this ...

   xlSheet.Cells(_row_, _column_)

And, when you're done ...

   xlBook.SaveAs ...
   xlBook.Close
   xlApp.Quit

If you want more detail, I suggest you ask in an Excel newsgroup - and
provide details about what is on your yserform and how you want it arranged
in a worksheet.
