Imagine receiving a file from a client, or your boss, with improperly delimited data. It's actually quite common. Just because someone can build a database, doesn't mean they can properly structure it. A common scenario is for the first and last name fields to be in the same column but you never know what you are going to encounter so it's best to be well versed with the text functions in FileMaker. In fact, data parsing can actually assist in creating features that weren't otherwise possible! That's why I consider data parsing one of the most important skill sets for database developers.
