    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.

Hi @PijushRoy

 

Here is another way just for your reference.

 

 

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]),
    res = let a=Table.ToColumns(Source),
              b=List.Distinct(a{0})
          in 
              Table.FromColumns(List.Split(a{1},List.Count(a{0})/List.Count(b)),b)
in
    res

Logic is:

  1. Split source table to two columns, the first is header name column and the second is data column.
  2. List.Distinct(first column) get the unique header names.
  3. List.Split(second column, pagesize=the count of table rows/the count of header names).
