Staring part of infornation in a columns
Hello, this is my problem. I have to send information with credit card
information. I need to star (****) out the middle 8 digits for security reasons. I would do this manually but there are over 10, 000 card numbers. Any help would be grateful.

You could use a helper column with a formula like:
=left(a1,4)&rept("*",8)&right(a1,4) You may have to adjust the lengths to match the format of your data (depending on the length of those credit card strings). Then drag this formula down the column as far as you need. Convert the formulas to values (edit|copy, edit|paste special|values) And delete the original column of credit card numbers. Make sure you delete that column--don't just hide it. Excel's security won't stop anyone from looking at a hidden column. Redseeing wrote: Hello, this is my problem.
