How to Stop a Worksheet_Calculate VBA Event from Looping

Question details

The user needs to stop a Worksheet_Calculate VBA procedure from continuously looping and eventually crashing the workbook.

Product: Spreadsheet
Device & OS: not provided
Scenario: A Worksheet_Calculate event is triggered after making workbook changes or unprotecting a worksheet, causing the code to endlessly call itself.
Observed behavior: The VBA procedure recursively executes in an infinite loop without stopping, which freezes or crashes the application.

Before you start

Before modifying your macro code, press Ctrl + Break (or Esc) to interrupt the running infinite loop, and save a backup copy of your workbook to prevent data loss.

Solution 1Recommended

Use Application.EnableEvents to Prevent Recursion

Temporarily disable application events at the start of your macro to prevent the calculation code from re-triggering itself, then re-enable them at the end.

When your VBA macro executes tasks that alter the worksheet or trigger a recalculation (such as unprotecting a sheet), the Worksheet_Calculate event is fired again instantly. This creates an infinite recursive loop. By toggling Application.EnableEvents off before executing your logic, you force the application to ignore event triggers until your code finishes processing.

Open the VBA Editor

Press Alt + F11 to launch the Visual Basic Editor, and locate the sheet containing your Worksheet_Calculate event code in the Project Explorer.

Disable Events at the Start

Insert the line 'Application.EnableEvents = False' at the very beginning of your Worksheet_Calculate procedure.

Add Error Handling

Add an 'On Error GoTo ErrorHandler' statement to ensure the code does not crash while events are disabled.

Re-enable Events at the End

At the bottom of your code, just before 'End Sub', insert 'Application.EnableEvents = True' to restore normal event listening.

Crucial Error Handling Step: If your macro throws an error and stops while EnableEvents is False, Excel/WPS will stop responding to all future events. Always ensure the 'Application.EnableEvents = True' line is placed inside your error handler block as well.

Frequently Asked Questions

Why does unprotecting a worksheet trigger the Worksheet_Calculate event?

Unprotecting a worksheet can force the application to refresh the workbook's state. If your workbook contains volatile functions (like TODAY, NOW, or OFFSET), this refresh inherently triggers a recalculation, which in turn fires the Worksheet_Calculate event.

What happens if I forget to set Application.EnableEvents back to True?

If EnableEvents remains False, the application will completely stop listening to all application-level and worksheet-level events. This means macros tied to Worksheet_Change, Workbook_Open, or SelectionChange will no longer run until you manually restore the setting.

How do I manually reset EnableEvents to True if my code crashes?

Open the VBA Editor (Alt + F11), press Ctrl + G to open the Immediate Window, type 'Application.EnableEvents = True', and hit the Enter key to instantly restore event functionality.
