Use the SUM function to sum numbers in a range
You can use a simple formula to sum numbers in a range (a group of cells), but the SUM function is easier to use when you’re working with more than a few numbers. For example =SUM(A2:A6) is less likely to have typing errors than =A2+A3+A4+A5+A6. Here’s a formula that uses two cell ranges: =SUM(A2:A4,C2:C3) sums the numbers in ranges A2:A4 and C2:C3.

Insert an object in your Excel spreadsheet - Microsoft Support
Insert a link to a file. You might want to just add a link to the object rather than fully embedding it. You can do that if your workbook and the object you want to add are both stored on a SharePoint site, a shared network drive, or a similar location, and if the location of the files will remain the same.
