Transpose Batch Excel Data

With Power Query/Get and Transform which is on the Data Tab. Here is the Mcode resulting from that transformation

let
    Source = Excel.CurrentWorkbook(){[Name="Table33"]}[Content],
    #"Demoted Headers" = Table.DemoteHeaders(Source),
    #"Changed Type" = Table.TransformColumnTypes(#"Demoted Headers",{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}, {"Column5", type number}, {"Column6", type number}, {"Column7", type number}, {"Column8", type number}, {"Column9", type number}, {"Column10", type number}, {"Column11", type number}, {"Column12", type number}, {"Column13", type number}}),
    #"Transposed Table" = Table.Transpose(#"Changed Type"),
    #"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Transposed Table", {{"Column1", type text}, {"Column2", type text}}, "en-US"),{"Column1", "Column2"},Combiner.CombineTextByDelimiter(":", QuoteStyle.None),"Merged"),
    #"Transposed Table1" = Table.Transpose(#"Merged Columns"),
    #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table1", [PromoteAllScalars=true]),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Origin City:", "Origin State:", "Destination City:", "Destination State:"}, "Attribute", "Value"),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Unpivoted Other Columns", "Attribute", Splitter.SplitTextByDelimiter(":", QuoteStyle.Csv), {"Attribute.1", "Attribute.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Attribute.1", Int64.Type}, {"Attribute.2", Int64.Type}})
in
    #"Changed Type1"

Review PQ steps

M-code basics:
- "let" is the start of a query
- "in" is the closing of a query
- each transformation step sits in between those 2 lines
- each step line is ended by a comma, except the last one
- "Source" is always the first step (Source Data)
- After "in" you have the last step referenced
