Is there a way to check if a Canadian postal code is in the correct format?

[Anonymous]

I have mailing addresses within a file and I'm trying to check the postal codes to ensure they follow the right format of A#A #A#. With Excel, I'd use the MID formula to return the specific character and manually review. Is there a Power Query function to check the format of postal codes and ensure they follow the guidelines of A#A #A#?

Thank you in advance! I've tried searching for this but couldn't find any solutions.

Hi, @Anonymous 

In powerbi, I would suggest you create a calculated column or measure.

You can use the MID function  to return the specific character and manually review.

Please check this official document.

You  can also try "split" feature in query editor as below:

@Anonymous , You can create a string with the format and compare, but not sure that can help https://docs.microsoft.com/en-us/powerquery-m/text-format

Text.Start Text.Middle and Text.End are good to use
