By default, Excel uses the "A1" format when referring to cells. This means that the "A" is the Column and the "1" is the Row that is being referred to. Most Excel users understand this; but some spreadsheet programs do not use this referencing.
Instead, other programs use the "R1C1" format when referencing cells. Excel allows for this format as well.
To specify the format you want to use, follow these steps.
Excel 2007:
Click on the "Office" button and select the "Excel Options" button.
Select the "Formulas" tab on the left menu.
Check the "R1C1 reference style" checkbox in the "Working with Formulas" section and click the "OK" button to save the changes.
Excel 2003: Click on the "Tools" menu and select the "Options" menu item. Follow the above instructions from here.
Excel 2010: Click on the "File" tab and select the "Excel Options" button. Follow the above instructions from here.
Notice the Column Headers are now numbers instead of letters.
NOTE: If you prefer the "A1" formatting and need to change Excel back to this preference, simply follow the above steps and uncheck the "R1C1" checkbox.
