Date Format Fix in Excel 2003

Due to an issue in Excel 2003, sometime the date formats are not updated in the cells, which leads to the problem, that a cell shows a date but is not read as a date by macros and formulas.

You could go through each cell, press 'F2' and 'Enter' and Excel would finally identify the content of the cell as a date. But this you would do manually and not by script.

With the following VBA script for Excel, the format can be updated:

Sub UpdateColumnFormat()

    Dim usedRangeOfRows As Integer
    usedRangeOfRows = ActiveSheet.UsedRange.Rows.Count
    
    'Date
    Columns("A:A").Select
    Dim e As Range
    Dim currentValueE As Date
    For Each e In Range("A2:A" & usedRangeOfRows).Cells
        e.Select
        currentValueE = ActiveCell.Value
        ActiveCell.FormulaR1C1 = currentValueE
    Next
    
End Sub

This problem occurs regularly, when I copy data from one sheet to another by VBA scripts.

With the above script, I could fix (at least work around it) this issue.

Enjoy :)
