I had a document the other day that I needed to search through on my Windows laptop and find specific number combinations that started with a specific three digits and ended with another digit. For example I had a list of thousands of numbers and needed to find any number that matched 333xxx4 where the xxx could be any number combination. At first I wasn’t sure what application I should use on Windows but then I remembered that Notepad++ had regular expression search and replace support. Below is an example of searching for the combination I mention above along with a list of other regular expressions that can be used for matching variables in documents opened with Notepad++.
It took me a lot of phone calls with AT&T technical support to try and figure out what the problem was with my 800 number however I finally got the correct answer. I wanted to post this information so hopefully if anyone else runs into this issue they will be able to get the correct quickly by locating this post.
