How to remove text strings stored in a list from a column

Hello carlpaul153 

check out this solution. this code replaces all substrings defined in the step SubstringList transforms the column1 into a list with two items. first is new value, second is the removed part. Then duplicated the column and transform them again. Extracting in the column1 the first item, in the changes-column the 2nd item

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckxKVorViVZKSU0D0+kZmWC6AgTArCoQUIqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    SubstringList = {"bc", "xx", "zzz"},
    TranformColumn1 = Table.TransformColumns
    (
        #"Changed Type",
        {
            {
                "Column1",
                (cell)=> List.Accumulate(SubstringList, {cell, ""}, (old, current)=> 
                let 
                    CreateNew = Text.Replace(old{0},current,""),
                    CreateSubstringsRemoved = try Text.Combine(List.Difference(Text.ToList(old{0}), Text.ToList(CreateNew))) otherwise ""
                in 
                    {CreateNew, if CreateSubstringsRemoved <> "" and old{1}<> "" then old{1} & ", " & CreateSubstringsRemoved else if old{1} <>"" and CreateSubstringsRemoved = "" then  old{1} else CreateSubstringsRemoved }
                )
            }
        }
    ),
    Duplicated = Table.DuplicateColumn(TranformColumn1, "Column1", "changes"),
    
    Final = Table.TransformColumns
    (
        Duplicated,
        {
            {
                "Column1",
                each _{0}
            },
            {
                "changes",
                each _{1}
            }
        }
    )
in
    Final
