I want to create either a macro or a UDF that can find cells in an excel worksheet that contains the following:
POxxx
PO xxxxxxx
PO# xxxxx
PO#xxxx
(With x being numbers)
The string could be at the start or the middle of cells.
In addition, the function/macro should not find cells that contain entries like CORPORATE, where PO is part of a word.

All the cells that contains qualifying data, should be highlighted.
