    Hi,

     

    You only need one table to solve this problem - the second one.  You will have to use the following M code in Power Query

     

    let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Items", type text}, {"Repeat till", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Start from", each 1),
    #"Reordered Columns" = Table.ReorderColumns(#"Added Custom",{"Items", "Start from", "Repeat till"}),
    #"Added Custom1" = Table.AddColumn(#"Reordered Columns", "Custom", each { Number.From([Start from])..Number.From([Repeat till]) }),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom1", "Custom"),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"Start from", "Repeat till"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Removed Columns",{{"Custom", type text}}),
    #"Added Custom2" = Table.AddColumn(#"Changed Type1", "Custom.1", each [Items]&[Custom]),
    #"Renamed Columns" = Table.RenameColumns(#"Added Custom2",{{"Custom.1", "Result"}}),
    #"Removed Columns1" = Table.RemoveColumns(#"Renamed Columns",{"Items", "Custom"})
in
    #"Removed Columns1"
