Let us see how this can be achieved using examples:
1. How to Run Excel Macro Automatically at Specific time?
To setup a Excel VBA timer event and schedule a macro to run at particular time, follow these steps.
Excel VBA - Schedule/Run Macro automatically at certain TimeVisual Basic12345678Private Sub Excel_VBA_Timer_Event()MsgBox "Automatic Scheduled Event: Good Morning"End SubPrivate Sub Schedule_Run_Macro_Specific_Date_Time()'Application.OnTime Schedule_Time,"Sub Procedure Name"Application.OnTime VBA.Now + TimeValue("00:00:01"), "VBA_Timer_Event"End Sub
- Press Alt+F11 from Excel to open VB editor.
- Click Menu -> Insert -> Module, to add new module in VBA Project.
- Copy & add the code in this page.
- Keep the cursor inside “Add_Schedule_Event_in_VBA()” procedure.
- Press F5 to activate time event.
This will automatically trigger the code, exactly at the scheduled time.
In 5 seconds, a message box will pop-up with the text you have entered in code. This way you don’t want to keep any remainders for certain tasks.
2. Timer in Excel – How to Run Macro Repeatedly at Certain Time Interval
Adding a vba timer event to a Excel Macro is similar to the scheduling macro.
But just that we need to mention the same procedure name to Application.Ontime function, as in below example.Excel VBA - Run Macro Repeatedly at Certain Time Interval1234Private Sub Excel_VBA_Timer_Repeated_Run_Macro()ThisWorkbook.Sheets(1).Cells(1, 1) = VBA.NowApplication.OnTime Now + TimeValue("00:00:01"), "VBA_Timer_Repeated_Event"End Sub
Copy paste this code into you module and press F5.
Now, go to the Sheet1 on the workbook and you can see that Cell A1 will have current system time and it will refresh every second.
This VBA timer event will keep on running the macro at certain time interval repeatedly. So, it will hinder the manual tasks that you are performing in any Excel file.
Before executing a timer event, save all your latest work in all the Excel workbook. Also, keep the interval for more than 5 seconds, while you activate this function for first time or while testing.
Timer in Excel & Scheduled VBA Macro
One could execute a VBA code either by using a User Interface (Clicking a command button) or Event Triggered (When user edit a value in cell) or Time Triggered.
