In Excel, visualizing the relationship between the cells used in a formula can be a powerful tool for understanding the spreadsheet’s structure and for debugging purposes. Here’s a tip on how to highlight all cells referenced in a formula in Excel:

Select the Cell Containing the Formula: Begin by selecting the cell that contains the formula you’re interested in. When a cell with a formula is selected, Excel provides a visual cue by using colored outlines around cells or ranges that are referenced in the formula.
Use the Trace Precedents Feature: For a more visual way of highlighting all cells used in your formula, you can use the “Trace Precedents” feature. You can access this by pressing “Alt”, then “M”, then “P” on your keyboard. This will create arrows that link the selected cell to the cells that provide data to it. Keep in mind that this feature only highlights direct precedents – cells that the selected cell directly references. If you want to display all cells that affect the value of the currently selected cell indirectly through multiple layers of formulas, press “Alt”, “M”, “P” again.
Use the Ctrl + [ Shortcut: Another efficient way to highlight cells in a formula in Excel is to use the Ctrl + [ keyboard shortcut after selecting the cell with the formula to show cells used in a formula. This shortcut will immediately select all cells directly referenced by the formula in the active cell. If the cells are on the same sheet, the screen will jump to include all the referenced cells. If the cells are on a different sheet, Excel will switch to that sheet.
Clear Traces or Selection: Once you’re done, and you want to remove the arrows created by “Trace Precedents” or clear the selection made by Ctrl + [, you can either click anywhere in the spreadsheet to clear the selection or press “Alt”, “M”, “A”, “A” to remove all arrows.

By utilizing these steps, you can effectively highlight cells in a formula in Excel, providing a clearer view of your formulas’ structure and dependencies.
