How about doing Tab Delimited and replacing the tabs with semi-colons?
In excel: File -> Save As -> in Format select “Tab Delimited Text (.txt)” then his save.
Open the file in notepad and open the replace window. Since you can’t tab directly into this window, copy a tab from your document and then paste it into the Find box and put your ; into the replace box. Then replace all.
I assume this would work because it is very rare to have tabs within an excel document.
