Duplicate rows based on a column value

• Unpivot the Experience Columns
• Replace the new experience column with its description in a List repeated the number of times represented by the value.
• Remove the Value column
• Expand the List column "To Rows"
• Note the optional line in case you don't want to expand the Response column, which seems to be just a total of the number of the other responses. If you want to also expand that, merely delete that code step (in the UI).
• Also, you do not show what you want for a result in the event the response is "0". I delete that row, but you could include it with a blank in the Experience column by deleting that step (in the UI).

let
    Source = Excel.CurrentWorkbook(){[Name="Table4"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{
        {"Division", type text}, {"Specialty", type text}, {"Month", type date}, 
        {"Very Good", Int64.Type}, {"Good", Int64.Type}, {"Neither", Int64.Type}, 
        {"poor", Int64.Type}, {"very poor", Int64.Type}, {"Don’t Know", Int64.Type},
         {"Response", Int64.Type}}),

//Optional in case you don't want to include the Response totals in your repeated final output
    #"Removed Response Total" = Table.RemoveColumns(#"Changed Type",{"Response"}),

    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Removed Response Total", 
        {"Division", "Specialty", "Month"}, "Experience", "Value"),

    #"Repeats" = Table.ReplaceValue(
        #"Unpivoted Other Columns",
        each [Experience],
        each [Value],
        (x,y,z) => List.Repeat({y},z),
        {"Experience"}
    ),
    #"Removed Columns" = Table.RemoveColumns(Repeats,{"Value"}),

//Optional to remove rows with "0" responses
    #"Remove Empties" = Table.SelectRows(#"Removed Columns", each not List.IsEmpty([Experience])),
    #"Expanded Experience" = Table.ExpandListColumn(#"Remove Empties", "Experience")
in
    #"Expanded Experience"
