define a storeDict:

 

 

then translate only the words your dict contains:

 

 

 

the code for dict:

 

let
    dict = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcsxNrMrPU9JRcivNU4rVAQrkpGSCuPn5KQrBJflFqWBR15TU7ERM4YD85Hyw3qK8zJJSmNrSovy0zBIjE6CMe2WuUmwsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Store = _t, Category = _t]),
    #"Changed Type" = Table.TransformColumnTypes(dict,{{"Store", type text}, {"Category", type text}})
in
 Record.FromList(dict[Category],List.Transform(dict[Store],Text.Lower))

 

 

the code to translate selected words:

 

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("LcvRCsIgAEbhV/nZbSEkvYA5cVFOybqosYuttGRsgen7F9LtxzldVzHFbrqFYVcl2rOFuJy0EbCEE0ZQi6pf/6JjvYdUuwYrcE1wkIVdjm8fEt1CzmNTSDzcNMCm7D02lBYzmmuIsMRwf6W8PD/z4OKU3P/qvw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"Bank transfer intended purpose" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Bank transfer intended purpose", type text}}),
Table.AddColumn(#"Changed Type", "Category", each Text.Combine(List.Transform(Text.SplitAny([#"Bank transfer intended purpose"], Text.Combine(List.Difference({" ".."@"},{"0".."9"}))), each Record.FieldOrDefault(storeDict, Text.Lower(_))),";"))
in
    #"Added Custom"

    Hi Anonymous ,

    you make a request for assistance, you get several answers and AFTER MORE THAN A MONTH, you write:
    "I just tried the code but it is not working properly."
    Aside from the fact that it is not clear what is not working, I believe that none of those who answered you remember anything about the subject.
    I'm sorry but I no longer want to reread the posts from a month ago.

      That's what I thought.
