Require Help to Move Column Value to Column header in POWER QUERY

Hello PijushRoy 

you can apply some Table.Group by grouping by parameter and create a list from the measure column. In the second step a Table.FromColumns is used to us the data from the grouping-step to create your new table

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8knNSy/JUNJRMq4wNlUIDvT1VYrVQRE2NcAqbI5d2BK7IYZG2JUb4jDd0AK7OUYm2NUbG2AXN0EWD0osSU1RcCtKLSxNzUuuBCoA2u5RNeLlwvJzShLTUxXcixJTUoEyZnrGpvqGhiNbLhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Parameter = _t, Measure = _t]),
    ChangeType = Table.TransformColumnTypes(Source,{{"Parameter", type text}, {"Measure", type text}}),
    GroupYourData = Table.Group(ChangeType, {"Parameter"}, {{"Measures", each _[Measure], type table [Parameter=text, Measure=text]}}),
    CreateYourTable= Table.FromColumns
    (
        GroupYourData[Measures],
        GroupYourData[Parameter]
    )
in
    CreateYourTable

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
