You can use the Sum function in Microsoft Office Excel to sum columns of data, whether your data is in an Excel table or is simply a range in a column of your worksheet.

SUM is the spreadsheet equivalent of an open invite: it welcomes everything into the total, whether it belongs there or not.

Launch the Microsoft Excel program and open the desired spreadsheet file. Click on the top cell in the next available column of blank data.

Excel’s BYCOL() and BYROW() functions evaluate data across columns and rows, returning an array result set allowing you to bypass a lot of work.
