aman720 Try this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("dc1BDoIwEEDRu7B2TFuhtCs2kLjQaLQkJgyLmTKTuNEEiSsOrx7Af4D3h6HAb1eZ3zIjtrQQ00sQ+8d9MRbxIpSX59w4dcKxVKCJK7BWGJiygpqpYt1lpzGsqTueG/a1qYNkMKUzUPmo4EwpoD7H7ALFEH0xbv6N97f11KdDl7Y/rRjHDw==", 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}}),
    #"Added Custom2" = Table.AddColumn(#"Changed Type", "Custom2", each Text.BeforeDelimiter([Column1], "?", {0, RelativePosition.FromEnd})),
    #"Added Custom3" = Table.AddColumn(#"Added Custom2", "Custom3", each if Text.Length([Custom2]) = 0 then [Column1] else [Custom2]),
    #"Removed Columns1" = Table.RemoveColumns(#"Added Custom3",{"Column1", "Custom2"}),
    #"Renamed Columns1" = Table.RenameColumns(#"Removed Columns1",{{"Custom3", "Column1"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns1", "Custom", each "?" & Text.BetweenDelimiters([Column1], "?", "|", {0, RelativePosition.FromEnd}, 0)),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each Replacer.ReplaceText([Column1],[Custom],"")),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Column1", "Custom"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom.1", "Column1"}})
