Filter out unique rows which follow the same text pattern

Hi Anonymous ,

Sorry for misunderstanding. For the sample data, the rows that you want to remove contain "-". If all the actual data is like this, you could try:

= if Text.Contains([Column1],"-") then null  else [Column1])

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("nc09CoQwEEDhu6Q2OJn8n2WxmCQTENHIEvb8a7NaCBZbPz7e6yVG2vc2b33lrY8MwNVnKxFTkByVkhSwSABEEwBCBBSDePPaPiym4cYN+ZS0JCB9cn9xcv6Rx5BtmKUp/91rOpCRrlA9OV3clPjEWZFGW2TlTD+u8OBQNAVXvHUPPLW2HHlh3u8xt61T7mefvg==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if Text.Contains([Column1],"-") then null  else [Column1])
in
    #"Added Custom"
