Power Query - Replace multiple substrings in one column

[Floriankx]

Hello,

I am looking for a solution to replace multiple substrings at once.

For Example:

Category	Category after
AA_A	AB_A
aa_B	AB_B
AA_C	AB_C
BB_A	DE_A
BB_B	DE_B
BB_C	DE_C

so AA->AB, aa->AB and BB->DE.

I found something here, but it is not able to replace substrings and it creates three single steps.

My aim would be to do it in one single step.

I'm really looking forward for your feedback.

Hi, @Floriankx 

Try the following M formula in Query Editor:

Text.Combine( List.ReplaceMatchingItems(

Text.Split ([Category], ”_“), { {“AA”, “AB”} , {“aa”, ”AB“} , {“BB” , “DE” } }

))
