VBA macro: MsgBox — Show a Message
Sub ShowMessage()
Dim ws As Worksheet
Dim cellValue As String
Set ws = ActiveSheet
cellValue = ws.Range("A1").Value
MsgBox "Value in A1: " & cellValue, vbInformation, "Cell Info"
End SubMsgBox displays a dialog with the message, an icon style (vbInformation/vbCritical/vbQuestion), and a title. Use it to confirm actions or show results.
How to run this macro
- Press Alt + F11 to open the VBA editor.
- Insert > Module.
- Paste the code above.
- Press
F5, or close the editor and run it from Developer > Macros. - Save the file as .xlsm so the macro is kept.
Open Excel and navigate to Developer ▸ Visual Basic (or press Alt + F11).
Select Insert ▸ Module from the menu bar inside the VBA editor.
Copy and paste Sub ShowMessage() into the Module.
Click anywhere inside the Sub body and press F5 to run.
Close the VBA editor and save the file as .xlsm.
What this does
Pasting Sub ShowMessage() into Excel's VBA editor gives you a one-click solution to show a message box popup with VBA. The macro runs inside the Visual Basic for Applications (VBA) environment, which lets it loop over entire sheets, inspect every cell, and take action faster than any manual workflow. Open the editor with Alt + F11, insert a new Module, paste the code, and run it — the MsgBox — Show a Message task completes automatically. Save the file as .xlsm (macro-enabled workbook) so the Sub is preserved when you close and reopen Excel. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. For “excel vba msgbox”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected cells change, and only then apply the same setup to the full sheet. 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 is what makes a workflow that saves repeating the same clicks every week useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
Practical use: you run the same show a message box popup with VBA task every month on a new export. Instead of repeating the steps manually, paste Sub ShowMessage() once into a Personal Macro Workbook (or into the workbook itself), and run it each month via Developer ▸ Macros ▸ Run. The MsgBox — Show a Message macro applies the same logic to every fresh dataset — consistent, repeatable, and immune to copy-paste slips. Use Sub ShowMessage() every time you need to show a message box popup with VBA reliably at scale. The macro eliminates the most common sources of error in manual work: missed rows, wrong column references, and inconsistent criteria. Once the code is tested and trusted, you can run it repeatedly with one click — zero cognitive overhead, zero variation in output. If this is something you do often, add the command to the Quick Access Toolbar (right-click it on the ribbon and choose Add to Quick Access Toolbar) or learn its shortcut, so next time it is one click instead of a hunt through the menus.
In Google Sheets
Google Sheets does not run VBA. A macro written for Excel has to be rewritten in Google Apps Script (Extensions ▸ Apps Script), and an .xlsm file converted to Sheets keeps its cells but drops the code. Keep this page bookmarked for the next time the same question comes up. Better still, repeat the steps once in your own workbook — doing it yourself is what turns a copied answer into something you remember. If you take one thing from this page on “excel vba msgbox”, make it the order of checks rather than the individual clicks: confirm what is selected, apply the step, and look at the result before moving on. That small routine is what keeps Excel work predictable when the same task comes back in a slightly different workbook.
Common mistakes
- Missing Option Explicit at the top of the module — adding it forces VBA to flag typos in variable names immediately, saving time debugging.
- Not qualifying the range with the worksheet object — using Cells(1,1) without a ws. qualifier acts on whatever sheet is active; if the macro runs from a different sheet it may corrupt data. The pattern `Dim ws As Worksheet: Set ws = ActiveSheet` (or a specific sheet name) pins the action to the right place.
- Forgetting that macros cannot be undone with Ctrl+Z once they have modified the sheet. Test on a copy of the workbook before running on live data.
Frequently asked questions
How do I run the MsgBox — Show a Message macro?
Press Alt + F11 to open the VBA editor, insert a Module (Insert ▸ Module), paste Sub ShowMessage() into the code pane, and press F5. Alternatively close the editor and run it from Developer ▸ Macros ▸ select "ShowMessage" ▸ Run.
Why won't my macro run — macros are disabled?
Excel blocks macros by default for files downloaded from the internet. Click the yellow security bar and choose "Enable Content" — that trusts this one workbook and is all that is normally needed. Leave File ▸ Options ▸ Trust Center ▸ Trust Center Settings ▸ Macro Settings on "Disable VBA macros with notification" rather than switching to "Enable all macros", which Microsoft itself marks not recommended. If the bar is red instead of yellow, the file carries Mark of the Web: close Excel, right-click the file, open Properties and tick Unblock. Also ensure the file is saved as .xlsm, not .xlsx.
Can I undo what the MsgBox — Show a Message macro did?
No — VBA actions generally cannot be undone with Ctrl+Z because they bypass Excel's undo stack. Always test Sub ShowMessage() on a backup copy of the workbook before running it on live data, or add explicit validation logic inside the macro before the destructive step.
