Adding Leading Zeroes to ZIP Codes

When you import ZIP Codes from a text file into an Excel workbook, it is not uncommon for Excel to translate the values as numbers rather than as ZIP Codes. This results in leading zeroes being dropped from the ZIP Codes, which can obviously cause problems later when using the data for its intended purpose.

One solution, of course, is to simply change the display format used for ZIP Code cells. (Excel provides a special format for ZIP Codes, available through the Number tab of the Format Cells dialog box.) This may work for the display, but the underlying data is still missing the leading zeroes.

If you want the underlying data to actually include the leading zeroes, it is best to use a macro that goes through and adds leading zeroes to the information in a cell. The following macro does just that:

Sub MakeZIPText()
    Dim ThisCell As Range

    Application.ScreenUpdating = False
    'Make sure format is text
    Selection.NumberFormat = "@"
    For Each ThisCell In Selection
        'Strip the leading apostrophe, if any
        If Left(ThisCell, 1) = "'" Then
            ThisCell = Mid(ThisCell, 2, 99)
        End If
        'It's a 5-digit ZIP Code
        If Len(ThisCell) <= 5 Then
            ThisCell = "'" & Right("00000" & ThisCell, 5)
        Else
            ThisCell = "'" & Right("00000" & ThisCell, 10)
        End If
    Next ThisCell
    Application.ScreenUpdating = True
End Sub

To use the macro, simply select the range of cells containing the ZIP Codes, then run the macro. The macro actually changes the cell contents—no longer will the cells contain numeric values (the cause of the original problem), but they will contain text values. This allows the leading zeroes to appear at the beginning of the ZIP Codes.

This tip's macro can be simplified a bit:

- "Strip the leading apostrophe" in the macro does nothing since Left(ThisCell, 1) = "'" doesn't detect the apostrophe and simply returns the first digit of the number because the leading apostrophe in Excel looks like an apostrophe but it isn't: it is a special character.

- Preceding the 5 or 10 digit zip code with an apostrophe isn't necessary because the cells are formatted as text.

- Although it does no harm, suppressing the screen updating isn't really necessary for a rather simple task like this.

So this 5 lines macro does the job as well:

Sub MakeZIPText()
Dim Cell As Range
Selection.NumberFormat = "@"
For Each Cell In Selection
Cell = Right("0000" & Cell, IIf(Len(Cell) > 5, 10, 5))
Next Cell
End Sub

Just wanted to confirm whether using text function in a helper column will give the same results..??

Like

=Text(A2,"00000")

0 can be repeated to reflect no. of total digits we need in the value including leading zeros..

In above formula 1234 will be changed to 01234 in the corresponding cell of helper column..
