Special Transpose to get output

[Anonymous]

Hi , I need to transpose a dataset to get a specific value.

Here is my Input table

Below is my output table.

For each ticket in the input table I need to get the key values as columns and its corresponding values as values in the table. Please note that I cannot directly use a transpose as the dataset is very huge.

Please help me with the above request and let me know if any more info is required or need further explanation.

@Greg_Deckler I forgot to check that dont aggregate option. Thanks it works now.

@Anonymous Can you just Pivot the Key column?

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQwVNJRcnQEEoZKsTpwAScgUZKRiizkDFJjZAwVMoJpMzJBFgHpS0xKRhaC6IOKGMNtQxEBaTMyNkEWAmlzdHFGFnIBEmUpSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Tickets = _t, Key = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Tickets", Int64.Type}, {"Key", type text}, {"Value", type text}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Key]), "Key", "Value")
in
    #"Pivoted Column"

@Greg_Deckler  I have tried this but I'm not getting the desired output as my dataset is huge, I'm just getting 0 and 1 in my output. The method of pivoting key field would work for small use cases. What do I do
