I recently had the same exact question and after struggling with creating my own tools and making them work correctly I found a great online ADDIN that's very EASY to USE.
This is the creator's excerpt
For my internship over the past several months I’ve been working in
the Marketing Science department and part of my job has been getting
data into MS Access and generating reports. This involves getting
lists of prospects from various data sources. This was usually a
pretty simple feat involving some basic SQL queries. However,
sometimes I was handed data such as addresses that didn’t match any
standard format used by IT. In the worst case the data was provided in
a pdf which meant I could only export it to a non-delimited text file.
I found that I really needed a couple generic regular expression
functions to parse out fields to import into MS Access. I found some
.xla examples online but I really wanted an easier to use, more
extensive, and portable library. I also wanted to include a few basic
patterns for so it wasn’t necessary to re-invent the wheel every time.
So, I created a simple Excel Add-In Regular Expressions.xla that adds
several custom functions to implement the standard VBScript regular
expressions.
Here is the website
I've used it successfully to extract useful text using regex.
Here's the code in the addin
