Extract Text Before Delimiter for multiple columns in a single query step

Hi there,

 

I have multiple columns in my data set that all require a query step that involves extracting text before delimiter (Text.BeforeDelimiter).

Is it possible to invoke this for all the required columns using just a single query step, or would I have to do the step for each column individually?

 

Thanks.

Select all of the columns you want to transform before applying Transform > Extract > Text.BeforeDelimiter and it should apply the step to all of the selected columns in a single step with M code that looks like this:

= Table.TransformColumns(Source,
      {
          {"Column1", each Text.BeforeDelimiter(_, "|"), type text},
          {"Column2", each Text.BeforeDelimiter(_, "|"), type text},
          {"Column3", each Text.BeforeDelimiter(_, "|"), type text}
      })

If you need to, you can edit each of these transformations separately (like if different columns use different delimiters or need an entirely different transformation).

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

Nice shot
