How to Use Macros in Excel

What this does

There are four practical ways to start a macro, and which one you want depends on who is doing the starting. Alt + F8 opens the Macros dialog listing every public Sub in every open workbook; select and click Run. That is the general-purpose route. F5 inside the editor runs whichever Sub the cursor currently sits in, which is what you use while building and testing. A keyboard shortcut can be attached under Alt + F8 ▸ Options — pick a letter with Ctrl + Shift rather than plain Ctrl, since plain Ctrl + letter combinations overwrite Excel's own shortcuts for that session. Finally, a button or shape with Assign Macro puts it in front of colleagues who will never learn any of the above. There is also automatic execution — event procedures in ThisWorkbook such as Workbook_Open run without anyone asking, which is powerful and worth being deliberate about. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “use macros in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected cells shows up while it is still harmless. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. That turns a workflow that saves repeating the same clicks every week into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

A workbook arrives with a macro called RefreshReport. Click Enable Content on the yellow bar, then press Alt + F8. The dialog lists RefreshReport; select it and click Run. To time it or watch it work, press Alt + F11 instead, click anywhere inside the Sub, and press F5 — that runs the same code but leaves you in the editor where Debug.Print output and any error dialog are visible. Paste Sub RunMeFromTheMacroDialog() into a module and run it both ways: A1 gets a timestamp and the dialog reports the elapsed time, so you can tell at a glance that it ran and how long it took. If the macro does not appear in the Alt + F8 list at all, it is Private, it takes arguments, or it lives in a sheet object rather than a standard module. Knowing all four entry points matters because they fail differently: F5 shows you the error, a button hides it, and a keyboard shortcut can collide with Excel's own. Picking the right one for the audience is most of what makes an automation usable by someone other than its author. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Treat “use macros in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.

Common mistakes

• Running a macro that modifies data without a backup. VBA writes bypass Excel's undo stack, so Ctrl + Z cannot recover anything a macro changed — test on a copy first, every time.
• Assigning a plain Ctrl + letter shortcut. It silently overrides the built-in shortcut for as long as the workbook is open, so Ctrl + C or Ctrl + S can stop doing what everyone expects. Ctrl + Shift + letter is the safe range.
• Expecting a macro from workbook A to find data in workbook B. Unqualified references like Range("A1") resolve against whatever is active at the moment the line executes, so which sheet you are looking at when you press Run changes the result.
• Concluding a macro is missing because Alt + F8 does not list it. Private Subs, Subs that take arguments, and code inside sheet objects are all hidden from that dialog while still being perfectly runnable with F5.
