Hello Ike and welcome to the forum.
Not sure I understand....
Have you copied the spreadsheet from your "old Vista computer" over to your new computer?
Do you have it stored on external media or cloud storage?
Do you have Excel or other software installed on the new computer to view and or edit the spread sheet?
What is the file extension.... .xls or .csv or something else?
