Power Query find matching and non matching values

Hi Anonymous 

You can put the following code to advanced editor in power query to as a reference.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSjRU0lECYfei1NQ8pVgdqJARppAxppAJppApilCSEYbxYCGo8ZUIEWMMERMMEVMMETO4SCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [OrderId = _t, ItemID = _t, Color = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"OrderId", type text}, {"ItemID", Int64.Type}, {"Color", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"OrderId"}, {{"MinColor", each List.Min([Color]), type nullable text}, {"MaxColor", each List.Max([Color]), type nullable text}, {"Data", each _, type table [OrderId=nullable text, ItemID=nullable number, Color=nullable text]}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"ItemID", "Color"}, {"ItemID", "Color"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Data", "Custom", each if [MinColor]=[MaxColor] then "same color" else " different color"),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"MinColor", "MaxColor"})
in
    #"Removed Columns"

Output
