I have a column with a lot of information in it from our clients. some of
the cells have credit card numbers in them. all i want to do is tell excel
to find any group of 4 numbers ex. 5689 or 4589 and delete it. here is a
breif example of what you may find in any given cell. the numbers are not
real BTW. i have 4 thousand cells like the one below, i cant change them it
would take too long, i just want excel to find groups of four numbers and
then change them so no one can see the phone numbers, cc numbers or ss numbers
thank you
