Hi,

This M code works

let
    Source = Csv.Document(File.Contents("C:\Users\mathu\Desktop\combined.csv"),[Delimiter=",", Columns=4, Encoding=1252, QuoteStyle=QuoteStyle.None]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Promoted Headers", {"Inventory Type", "Dealer Part"}, "Attribute", "Value"),
    #"Added Index" = Table.AddIndexColumn(#"Unpivoted Other Columns", "Index1", 1, 1, Int64.Type),
    #"Grouped Rows" = Table.Group(#"Added Index", {"Inventory Type", "Dealer Part", "Attribute"}, {{"Count", each Table.AddIndexColumn(_,"Counter",1,1), type table [Inventory Type=nullable text, Dealer Part=nullable text, Attribute=text, Value=text, Index1=number, Counter=number]}}),
    #"Expanded Count" = Table.ExpandTableColumn(#"Grouped Rows", "Count", {"Value", "Index1", "Counter"}, {"Value", "Index1", "Counter"}),
    #"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Expanded Count", {{"Counter", type text}}, "en-IN"),{"Attribute", "Counter"},Combiner.CombineTextByDelimiter(" ", QuoteStyle.None),"Merged"),
    #"Sorted Rows" = Table.Sort(#"Merged Columns",{{"Index1", Order.Ascending}}),
    #"Removed Columns" = Table.RemoveColumns(#"Sorted Rows",{"Index1"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Merged]), "Merged", "Value")
in
    #"Pivoted Column"

Hope this helps.

This is just fantastic!!! Can you please explain me the reason to get index column? I know it works in the end run, but I couldn't quite grasp the reason to get index column and steps after that. Thank you so much!

You are welcome.  The sole purpose of that column is to use it to sort the table in ascending order (before Pivoting back).

@Anonymous , First unpivot other by seleting Inventory Type | Dealer Part

Then Split by Delimiter using _

and then pivot again
