Hi Harriet,

Thanks for using the Import-O-Matic Forums.  You can try doing the following:

Replacement Value:  Visa 
Value to Match On:  V.*

This will insert the word Visa when the text is formatted like V-XXXX2222.  Please be sure to check the Use Regular Expressions checkbox at the bottom of the screen.  

You can use the same formula format for the other credit types that you have.  I hope you find this information helpful.  Please let us know if you have any additional questions.

Best,

Callie
