Good, so you add the category-field to the unpivot others step:

// Table1
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Filtered Rows2" = Table.SelectRows(Source, each ([Column1] <> null)),
    #"Added Custom" = Table.AddColumn(#"Filtered Rows2", "Week", each if Text.StartsWith([Column1], "Week ") then [Column1] else null),
    #"Filled Down" = Table.FillDown(#"Added Custom",{"Week"}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Filled Down", [PromoteAllScalars=true]),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Week 1", "Week 1_1", "category"}, "Attribute", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Other Columns",{{"Attribute", "Date"}}),
    #"Filtered Rows" = Table.SelectRows(#"Renamed Columns", each not Text.StartsWith([Week 1], "Week ")),
    #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", each ([Value] <> "")),
    #"Renamed Columns1" = Table.RenameColumns(#"Filtered Rows1",{{"Week 1", "Row"}, {"Week 1_1", "Week"}}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns1",{{"Value", type number}, {"category", type text}})
in
    #"Changed Type1"

Hi VincenzoChean ,
will there always only be 7 columns with dates or could there be more or less? (This is relevant for how to determine the columns that shall be unpivoted.)
With regards to the m-code, in this video I show how to use code from the internet and paste it into the advanced editor: Dynamically solve parent child hierarchies in Power BI and Power Query - YouTube

Hi VincenzoChean ,
please paste the following code into the advanced editor and follow the steps:

let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], #"Filtered Rows2" = Table.SelectRows(Source, each ([Column1] <> null)), #"Added Custom" = Table.AddColumn(#"Filtered Rows2", "Week", each if Text.StartsWith([Column1], "Week ") then [Column1] else null), #"Filled Down" = Table.FillDown(#"Added Custom",{"Week"}), #"Promoted Headers" = Table.PromoteHeaders(#"Filled Down", [PromoteAllScalars=true]), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Week 1", "Week 1_1"}, "Attribute", "Value"), #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Other Columns",{{"Attribute", "Date"}}), #"Filtered Rows" = Table.SelectRows(#"Renamed Columns", each not Text.StartsWith([Week 1], "Week ")), #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", each ([Value] <> "")), #"Renamed Columns1" = Table.RenameColumns(#"Filtered Rows1",{{"Week 1", "Row"}, {"Week 1_1", "Week"}}), #"Changed Type1" = Table.TransformColumnTypes(#"Renamed Columns1",{{"Value", type number}}) in #"Changed Type1"

    Hi VincenzoChean ,
    
    Below transformation code should be dynamic enough to turn the data into structured data formate:
    
    let
    
    //Get Source
    Source = Excel.CurrentWorkbook(){[Name="Table2"]}[Content],
    //Unpivot other column other than the first one (i.e. week1,2, column)
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Column1"}, "Attribute", "Value"),
    //Add conditional column to get "Week", then fill down
    #"Added Custom1" = Table.AddColumn(#"Unpivoted Other Columns", "Custom", each if Text.StartsWith([Column1],"Week") then [Column1] else null),
    #"Filled Down" = Table.FillDown(#"Added Custom1",{"Custom"}),
    //Filter for only the header rows
    ColumnTbl = Table.SelectRows(#"Filled Down", each Text.StartsWith([Column1],"Week")),
    //Filter for all row except header rows
    NonColumnTbl = Table.SelectRows(#"Filled Down", each not Text.StartsWith([Column1],"Week")),
    //Join the main table (the content without header) with header table to get table
    #"Merged Queries" = Table.NestedJoin(NonColumnTbl, {"Custom", "Attribute"}, ColumnTbl, {"Custom", "Attribute"}, "NonColumnTbl", JoinKind.LeftOuter),
    #"Expanded NonColumnTbl" = Table.ExpandTableColumn(#"Merged Queries", "NonColumnTbl", {"Value"}, {"Date"}),
    //Rename header (rename to whatever name you want)
    #"Renamed Columns" = Table.RenameColumns(#"Expanded NonColumnTbl",{{"Column1", "Measure / Title"}, {"Custom", "Week Number"}}),
    //Remove access columns
    #"Removed Columns1" = Table.RemoveColumns(#"Renamed Columns",{"Attribute"})
    
    in
    #"Removed Columns1"

= Table.Combine(Table.Group(Source,"Column1",{"n",each let a=Table.PromoteHeaders(Table.SelectRows(_,each [Column1]<>null)),b=Table.UnpivotOtherColumns(a,List.RemoveRange(Table.ColumnNames(a),1,7),"Date","x") in Table.RenameColumns(Table.Pivot(b,List.Distinct(Table.ToColumns(b){0}),Table.ColumnNames(b){0},"x"),{{"dates","category"}},1)},0,(x,y)=>Byte.From(Text.StartsWith(y??"","Week ")))[n])
