Wildcard Search and Replace
- 
Hello.
I am trying to find any field that is 16 digits long that starts with 123456 and replace it with 123456XXXXXXXXXX.
Here is a snapshot of what I am trying to accomplish.

I tried 123456.*, but it replaced everything to the right of that field. I just need that specific field updated.
Any assistance you could provide would be appreciated. Thanks.

Very close. The
*quantifier means “0 or more”. What you want is a quantifier that gives an exact number of digits… in this case,123456.{10}, which says “123456followed by exactly 10 other characters”.You might change it to
123456\d{10}, which says “123456followed by exactly 10 numerical digits”.----
