Question: In Microsoft Excel 2016, my Excel spreadsheet has numbers for both rows and columns. How do I change the column headings back to letters such as A, B, C, D?

Answer: Traditionally, column headings are represented by letters such as A, B, C, D. If your spreadsheet shows the columns as numbers, you can change the headings back to letters with a few easy steps.

In the example below, the column headings are numbered 1, 2, 3, 4 instead of the traditional A, B, C, D values that you normally see in Excel. When the column headings are numeric values, R1C1 reference style is being displayed in the spreadsheet.

To change the column headings to letters, select the File tab in the toolbar at the top of the screen and then click on Options at the bottom of the menu.

When the Excel Options window appears, click on the Formulas option on the left. Then uncheck the option called "R1C1 reference style" and click on the OK button.

Now when you return to your spreadsheet, the column headings should be letters (A, B, C, D) instead of numbers (1, 2, 3, 4).
