Sort columns contains weeks values

Hello Anonymous 

try this. Add a column where you extract the first part, transform it to a date, sort it and then remove the date column

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Pc1LDsAgCEXRrRjHbeQTrazFuP9t+FqgI5LLCaxVSRrNcheamHVfKKORoTA25sXccE/DGsbS8HAjkkY0iv0F5nl/cRal+N6/O/sA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    ChangeType = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    AddDateColumn = Table.AddColumn(ChangeType, "Custom", each Date.From(Text.Split([Column1]," - "){0})),
    SortDate = Table.Sort(AddDateColumn,{{"Custom", Order.Ascending}}),
    RemoveDate = Table.RemoveColumns(SortDate,{"Custom"})
in
    RemoveDate
