Unpivot / transpose / amend a Single Row

[Saes]

Hi all, I have a multiple datasets (about 20 tables) that look like this - annoyingly the output puts the units in row 2.

Sub Company	Measure 1	Measure 2	Measure 3
Units	Number	%	Number
Company 1	10	0.5	10
Company 2	20	0.6	20
Company 3	30	0.7	30
Company 4	40	0.8	40
Company 5	50	0.9	50

I would like to clean the data so that the data looks as follows, but I cannot work out how to unpivot / transpose / amend the unit row, before unpivotting the measure columns.

Sub Company	Units	Attribute	Value
Company 1	Number	Measure 1	10
Company 1	%	Measure 2	0.5
Company 1	Number	Measure 1=3	10
Company 2	Number	Measure 1	20
Company 2	%	Measure 2	0.6
Company 2	Number	Measure 1=3	20

Can anyone help?

Thanks @serpiva64 - that worked perfectly. Thank you!

Hi, 

you can obtain this

by

- demote headers

- transpose table

- promote headers

- unpivot columns

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCs3LLClW0lHyK81NSi0CMlQRnFidaCXn/NyCxLxKBUOgsKEBkDDQM4UwkWWNgEJGEFkzCBNZ1hgoZAyRNYcwkWVNgEImEFkLCBNZFmSZKUTWEsKMjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Sub Company" = _t, #"Measure 1" = _t, #"Measure 2" = _t, #"Measure 3" = _t]),
#"Demoted Headers" = Table.DemoteHeaders(Source),
#"Transposed Table" = Table.Transpose(#"Demoted Headers"),
#"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", [PromoteAllScalars=true]),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Sub Company", "Units"}, "Attribute", "Value"),
#"Renamed Columns" = Table.RenameColumns(#"Unpivoted Columns",{{"Attribute", "SubCompany"}, {"Sub Company", "Attribute"}}),
#"Sorted Rows" = Table.Sort(#"Renamed Columns",{{"SubCompany", Order.Ascending},{"Attribute", Order.Ascending}}),
#"Reordered Columns" = Table.ReorderColumns(#"Sorted Rows",{"SubCompany", "Units", "Attribute", "Value"})
in
#"Reordered Columns"

Hi @Saes ,

Here's one way to do it. It involves a few custom steps/adjustments but is fairly simple and tidy:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCs3LLClW0lHyK81NSi0CMlQRnFidaCXn/NyCxLxKBUOgsKEBkDDQM4UwkWWNgEJGEFkzCBNZ1hgoZAyRNYcwkWVNgEImEFkLCBNZFmSZKUTWEsKMjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Sub Company" = _t, #"Measure 1" = _t, #"Measure 2" = _t, #"Measure 3" = _t]),
    unpivOthCols = Table.UnpivotOtherColumns(Source, {"Sub Company"}, "Attribute", "Value"),
    getUnitsTable = Table.SelectRows(unpivOthCols, each [Sub Company] = "Units"),
    getDataTable = Table.SelectRows(unpivOthCols, each [Sub Company] <> "Units"),
    mergeUnitsOnData = Table.NestedJoin(getDataTable, {"Attribute"}, getUnitsTable, {"Attribute"}, "getDataTable", JoinKind.LeftOuter),
    expandUnitsValue = Table.ExpandTableColumn(mergeUnitsOnData, "getDataTable", {"Value"}, {"Value.1"})
in
    expandUnitsValue

Summary:

-1- Unpivot columns other than [Sub Company]

-2- Split into two tables, one with just [Sub Company] = "Units", the other with everything else

-3- Merge Units table onto Other Data table on U.Attribute = OD.Attribute

-4- Expand OD.Value

Output:
