Solution 1Recommended

Disable R1C1 in the Personal Macro Workbook (PERSONAL.XLSB)

Use this solution if you utilize macros, as the PERSONAL.XLSB file may be forcing the R1C1 reference style to load globally.

The Personal Macro Workbook loads in the background every time you start Excel. If it was accidentally saved with R1C1 enabled, it will force all subsequent workbooks to adopt this style.

1
Unhide the Personal Macro Workbook

Open Excel. Navigate to the 'View' tab on the ribbon, click on 'Unhide' in the Window group, select 'PERSONAL.XLSB', and click 'OK'.

2
Change the Reference Style

Go to 'File' > 'Options' > 'Formulas'. Under the 'Working with formulas' section, uncheck the box for 'R1C1 reference style' and click 'OK'.

3
Save and Hide

Click the 'Save' icon in the top-left corner. Then, go back to the 'View' tab and click 'Hide' to conceal the Personal Macro Workbook again.

4
Restart Excel

Completely close the Excel application and reopen it to verify that new workbooks now use the standard A1 reference style.

Disable R1C1 in the Personal Macro Workbook (PERSONAL.XLSB)
Macro settings preserved: Hiding the PERSONAL.XLSB file does not disable your macros; it merely keeps the background workbook out of your way while retaining the correct formula style.

Frequently Asked Questions

What is the difference between A1 and R1C1 reference styles?

In the standard A1 reference style, columns are labeled with letters (A, B, C) and rows with numbers (1, 2, 3). In the R1C1 reference style, both rows and columns are labeled with numbers (for example, R1C1 indicates Row 1, Column 1). While R1C1 is helpful for specific macro programming tasks, A1 is the preferred standard for everyday spreadsheet users.

Why did my Excel suddenly switch to the R1C1 style?

This typically occurs if you open a file that was saved by another user with the R1C1 setting turned on. Excel may adopt that file's settings. It can also happen if a background macro or a custom default template (like Book.xltx) overrides your application's default settings.

How do I temporarily switch between A1 and R1C1 styles?

You can toggle the reference style manually at any time. Go to File > Options > Formulas, and under the 'Working with formulas' section, simply check or uncheck the 'R1C1 reference style' box and click OK.
