    You can try something like the following.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclRIzEtRcFLSUTJUitVB5huB+c5AljGY5QJkmYBZrkCWKZgVAVYdCeSbofHNlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Key = _t, Value = _t]),
    #"Grouped Rows" = Table.Group(Source, {"Key"}, {{"AllRows", each _[Value], type table [Key=nullable text, Value=nullable text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "NewKey", each [Key], type text),
    #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(#"Added Custom", {{"NewKey", Splitter.SplitTextByDelimiter(" and ", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "NewKey"),
    #"Added Custom1" = Table.AddColumn(#"Split Column by Delimiter", "Position", each [AllRows]{List.PositionOf(Text.Split([Key], " and "), [NewKey])}, type text),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Key", "AllRows"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"NewKey", "Key"}, {"Position", "Value"}})
in
    #"Renamed Columns"

RitaHL Question, why not:

A 1

A 2

B 1

B 2

C 3

D 4

...

 

Because that's pretty easy like so:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclRIzEtRcFLSUTJUitVB5huB+c5AljGY5QJkmYBZrkCWKZgVAVYdCeSbofHNlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Key = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Key", type text}, {"Value", Int64.Type}}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Changed Type", "Key", Splitter.SplitTextByDelimiter(" and ", QuoteStyle.Csv), {"Key.1", "Key.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Key.1", type text}, {"Key.2", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"Value"}, "Attribute", "Value.1"),
    #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"})
in
    #"Removed Columns"
