let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],

    
    AddCustomColumn = Table.AddColumn(Source, "ExpandedRange", each let
        RangeStart = Text.Middle([Column A], 1, Text.PositionOf([Column A], "-") - 1),
        RangeEnd = Text.Middle([Column A], Text.PositionOf([Column A], "-") + 1),
        StartNumber = Number.From(Text.Remove(RangeStart, {"A".."Z"})),
        EndNumber = Number.From(Text.Remove(RangeEnd, {"A".."Z"})),
        Prefix = Text.Remove(RangeStart, {"0".."9"}),
        RangeList = List.Transform({StartNumber..EndNumber}, each Prefix & Text.From(_))
    in
        RangeList),
    
    ExpandColumn = Table.ExpandListColumn(AddCustomColumn, "ExpandedRange"),

    RemoveOriginalColumn = Table.RemoveColumns(ExpandColumn, {"Column A"}),

    RenameColumns = Table.RenameColumns(RemoveOriginalColumn, {{"ExpandedRange", "Column A"}})

in
    RenameColumns
