Re: data transformation

hi, @yakm

Based on my test, you could tr these step in Edit Queries:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTLUNzTUNzIwtASyi1JTlGJ14OJGMPGknNJUsIQRRMIYXQNU3ARZg056UWpqnlJsLAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, Date = _t, category = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Date", type date}, {"category", type text}}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Changed Type", "category", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"category.1", "category.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"category.1", type text}, {"category.2", type text}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"ID", "Date"}, "Attribute", "Value"),
    #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Other Columns",{"Attribute"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Value]), "Value", "Date")
in
    #"Pivoted Column"

Result:

let
    Source = Mail,
    #"Filtered Rows" = Table.SelectRows(Source, each ([New_or_revisit] <> null) and ([case_type] = "CF")),
    #"Removed Columns2" = Table.RemoveColumns(#"Filtered Rows",{"Subject", "Folder Path", "Sender.Address", "Importance", "Index", "New_or_revisit", "case_type"}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Removed Columns2", "Categories", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"Categories.1", "Categories.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Categories.1", type text}, {"Categories.2", type text}}),

Re: data transformation

hi, @yakm

Add a group index column for 

let
    Source = Mail,
    #"Filtered Rows" = Table.SelectRows(Source, each ([New_or_revisit] <> null) and ([case_type] = "CF")),
    #"Removed Columns2" = Table.RemoveColumns(#"Filtered Rows",{"Subject", "Folder Path", "Sender.Address", "Importance", "Index", "New_or_revisit", "case_type"}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Removed Columns2", "Categories", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"Categories.1", "Categories.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Categories.1", type text}, {"Categories.2", type text}}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"sCRM_ID", "DateTimeReceived.1"}, "Attribute", "Value"),
    #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Other Columns",{"Attribute"}),
    Partition = Table.Group( #"Removed Columns" , {"sCRM_ID"}, {{"Partition", each Table.AddIndexColumn(_, "Index",1,1), type table}}),
#"Expanded Partition" = Table.ExpandTableColumn(Partition, "Partition", {"DateTimeReceived.1", "Value", "Index"}, {"DateTimeReceived.1", "Value", "Index"}),
#"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Value]), "Value", "DateTimeReceived.1"), #"Removed Columns1" = Table.RemoveColumns(#"Pivoted Column",{"Data completed"}) in #"Removed Columns1"
