Hi,

Have you read and tried the code from these posts

https://www.myonlinetraininghu.....ower-query

https://www.myonlinetraininghu.....ower-query

You haven't said how you want the results to look so I've produced a table with the strings that match in a separate column - see attached.

Regards

Phil

You can also try this query, might be faster:

let
Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
WordList = List.Buffer(Excel.CurrentWorkbook(){[Name="WordList"]}[Content][Parent Item]),
#"Added Custom1" = Table.AddColumn(Source, "Custom", (x)=> Text.Combine(List.Select(WordList, each Text.Contains(x[item], _ ,Comparer.OrdinalIgnoreCase) ),","))
in
#"Added Custom1"

You can remove the red argument if Case should not be ignored.
