If the zip is in its own column, A for example, you might use a helper
column. For a zip such as 1234 which should be 01234 you could use a formula
like
=IF(LEN(A1)=4,"0"&A1,A1). For a zip such as 1234-5678 You could use
=IF(LEN(A1)=9,"0"&A1,A1)
The results of both formulas will be text. If you're satisfied with the
results, you can delete column A and use the helper column as the zip code.

I'm using excel to open an XML file of address, but it truncates the
leading zero if a zip begins with one. I don't have the option of
modifying the source file and putting in an apostrophe. Is there a way
around this?
