Of course it is possible. Here is an example M code how to do that in Power Query:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ndKxCoMwEAbgd8ksohdN5y527VDoIA5BQwnYCufSx28oKZHmzqQdJEL4uPvv0vcCoDyUUEElCnExT726s3bf1aKZ3Hm8G7Sjdn/yfTMUtAHSNKQ5mQVvVrOV2oT6r5b0ajbrmlHurNF+B+tQP0bj++aJzCfdvKCdtqGi9iAB2Vz0wgJsyDFu+qz5pxEV22dsuH0myQ4lacKi2x9yBaVIBaSKt5bTYbwy9tmT6pMrGqJKQMVBP5PhBQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Name = _t, Code = _t, #"Connection Type" = _t, Country = _t, Calls = _t, Invalid = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Name", type text}, {"Code", type text}, {"Connection Type", type text}, {"Country", type text}, {"Calls", Int64.Type}, {"Invalid", Int64.Type}}),
#"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"Code"}),
#"Grouped Rows" = Table.Group(#"Removed Columns", {"Date", "Name", "Connection Type", "Country"}, {{"Calls", each List.Sum([Calls]), type text}, {"Invalid", each List.Sum([Invalid]), type text}})
in
#"Grouped Rows"
Table.RemoveColumns
will remove the Code
column and Table.Group
will group the data on the specified columns (Date
, Name
, Connection Type
and Country
) and aggregate the data, sum in this case (Calls
and Invalid
).
You can do this using the UI only. In Power Query Editor, right click the title of Code
column and select Remove
. Then from Transform
tab click on the leftmost button Group By
and fill it as follows:
