Split lines in rows to table M Query

My source is PDF file, in source it like matrix, and I need to create table like KEY-VALUE. To make more clear I create a sample:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XYo9DoAgDEbv0sTN8I/UkR0TBzbKFXr/0Zq64PDy+vJ1DGiZuCHx3YUg94sXIjEmizKFRFxOIVuU79qIrw47OOPcRvzJm6jKqrTUsZRXBVX5F8z5AA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t])
in
    Source

 As you can see, there are one raw with data in several lines with [Line Feed} in end of each line. I need generate separate raw from each line, like this sample:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8jFV0lEy0DMwUFWK1QFyLVC4ASFArqGeMYxrBOaawhRDuCZAXiwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t])
in
    Source

 Basic split by delimiter is not appropriate, because it's create for each line in Column 1 the same value in Column2.
