Check if column text contains values from another column and return the text

[cerebro]

Dear everybody,

I have two different sources and i would like to search for the project number from the second source in the account from the first source and return the project in the custom column:

Based on the solutions to similar problems i've tried to add a custom column like this:

= Table.AddColumn(#"PreviousStep", "ProjectNumber", each List.Contains(Text.Split([Account], "-"), Source2 [Project])))

But the part Source2 [Project]))) is not working

Can someone please correct my formula or suggest any other ?

Thank you in advance.

You'll need to take a different approach for this but this line will do it (in a new custom column)

= let _account = List.Select(Text.Split([Account], "-"), each Text.Length(_) = 4) in

if List.Count(_account) > 0 then _account{0} else null

thanks a lot, your formula works (but only without the {0}).

I have 200-300 k lines and power query takes a while to finish it, but it works 😊

If your Account in Source1 always contains only one 4 digit project code (or none), then you can extract it using this.  No lookup to Source2 needed.

= Text.Select([Account], {"0".."9"})

If the Account in Source1 might also contain numbers that are not Project Codes, you could use this which does check against Source2

= if List.Contains(Source2[Project],Text.Select([Account], {"0".."9"})) then Text.Select([Account], {"0".."9"}) else null

thank you for the elegant solution.

Yes in fact, there are some other numbers that do not represent a project number and if you replace any letter with a number, the second formula doesnt work anymore:

Can you fix it? Thanks again!

Yes, you can use Text.BetweenDelimiters to extract just the 4 digits between the - -

= Text.Select(Text.BetweenDelimiters([Account], "-", "-"), {"0".."9"})

sorry to bother you again, but could you please edit the formula that it returns a match even when the project number is not in the middle of the text string ? thanks again for your help!
