Check naming convention of data

[Franny_Spanny]

Hi all, 

I am trying to find a way to check a standardised naming convention. 

We use a standard file naming format of:

??????-????-???-???-??-??-?-????

Project-Code-Originator-Volume-Level-Type-Discipline-Number

I would like to check a whole column of file names against the above standard. 

I really have no idea where to start with this - I already have checks that check each individual section between delimiters against a picklist (ie. Originator code exists in list, Volume code exists in list etc.) but I'm not sure where to start with checking the whole file name.

I know that we cannot use 'wildcards' such as ?? or * in PowerBI or PowerQuery so I'm a little stumped as the best way to achieve this.

Any help much appreciated!

@Franny_Spanny Is using DAX an option? Another option would be to add a Python or R step to the query and use regex.

@Greg_Deckler absolutely okay for DAX. Python is possible.

R not an option due to this being work related and unfortunately unable to get R installed due to lots of red tape!

Hey @Greg_Deckler, not sure if you saw my whole reply as it was a later edit, so just wanted to tag again just in case 🙂
