Extract url from text in DAX

Hi everyone

 

I'm trying to extract urls from twitter messages and placing in another column using DAX. I've been using this formula in excel to extract and it works fine:

 

=MID(A1,FIND("http",A1),IFERROR(FIND(" ",A1,FIND("http",A1))-1,LEN(A1))-FIND("http",A1)+1)

 

However I'm strugging to replicate/see how to do this in DAX. Any help greatly appreciated!

 

Thanks

 

Ben

Thanks again!

I agree, you need to post an example. But I also think this is a task for data shaping in power query (get data) and not DAX.

Hi

 

Thanks for getting back to me and good point on power query.

 

Screen grab of examples below - as you can see the urls aren't always in the same spot:

Re: Extract url from text in DAX

How about using power query to split column on colon :  then rebuild the URL http:// from there

Hi Matt

 

Thanks for this - will do. Apologies for my ignorance but is there anyway I can bring across to power query the actual excel formula I have?

 

Regards

No way unfortunately. But using the power query UZi is much easier than writing Excel formulas.

Hi

 

I'm giving the Power Query option a go but your screen shot look good - basically where ever there is a url it gets taken out and put in another column (s).

 

Thanks
