Remove Unwanted text from Date Columns

If the date in the string is separated from other elements by a space, try adapting this example to your data:

let

//sample table
    Source = Table.FromColumns({
        {"01/04/2022",
          "N/A",
          "PROCESSED DATE: 03/11/2022"}},
          type table[processed_date=any]),

    #"Dates Only" = Table.TransformColumns(Source,{"processed_date", (e)=> 
        List.Sort(
            List.Transform(
                Text.Split(e," "), 
                    each try Date.From(_, "en-US") otherwise "")){0}, type date})
in
    #"Dates Only"
