You can use workbook events to turn on and off the user's system setting, and restore the setting back to the original value when you're done.

In the ThisWorkbook object, put an Open event that takes note of their initial setting and then turns it off.

Dim MyErrorCheckValue as Boolean

Private Sub Workbook_Open()
    MyErrorCheckValue = Application.ErrorCheckingOptions.NumberAsText
    Application.ErrorCheckingOptions.NumberAsText = False
End Sub

Add a BeforeClose event to set it back to original value when closing the file.

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    Application.ErrorCheckingOptions.NumberAsText = MyErrorCheckValue
End Sub

Then add Activate and Deactivate events so it switches when the user opens or views a different spreadsheet.

Private Sub Workbook_Activate()
    Application.ErrorCheckingOptions.NumberAsText = False
End Sub

Private Sub Workbook_Deactivate()
    Application.ErrorCheckingOptions.NumberAsText = MyErrorCheckValue
End Sub

You could add similar events at the sheet level to turn it on and off when switching sheets within the workbook.

Would also be wise to add some error handling that sets it back to original value so you don't accidentally leave it in the wrong state in the unlikely event that your code bugs out somewhere.
