Is there a way to make Filemaker recognize phone numbers in a text field and/or web site and extract that data into the database?
It's possible, but may not be simple to do. Much depends on how many different formats to the phone number might be encountered.
555-555-5555 ext 304
555 555 55555
are just some of the possible phone number formats.
There are several customer functions that do that for you FileMaker Pro Custom Functions
This is a classic case where a regular expression makes phone number recognition (say US Only) straightforward as opposed to a long drawn out CF. Sadly, and IMHO surprisingly, FMP 16 still doesn't directly support regular expressions.
I wrote a simple RegEx matcher using a micro-service, but I've found few folks here are willing to do Java.
Fortunately, there are some plug-ins that support RegEx as well.
I'd start with a program like RegExRx where you can craft your RegEx.
If you do some searches, you'll find TONS of examples using RegEx to filter phone numbers. A very common need.
