Convert a list into multiple column table

Thank for parry2k's concern about this issue.

Hi, KelvinUceta 

I am glad to help you.

Maybe you can refer to my M code.
Open Power BI Desktop-->select transform data-->right click New blank query in Queries panel-->select Advanced Editor while copying the following M code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCsnMTVWK1YlWCkotLE0tLoGyiwvy84ohEs45mal5EHFzKwNTKyMTMNtS39BM38gAyisoyq+o1MutdM5M1EvOzwWLhVQWpFopOAKBjkJATmJmnoKLXzBYJqAoPzm1uDg1Bcwz0DMwU8gtBrMNDfSMzPSMjfRMjMF830q//JRUTxfyraeG3bEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column = _t]),
    tolist = Table.ToList(Source),
    columnnames = List.FirstN(tolist,4),
    values = List.Range(tolist,4),
    IndexedList = List.Zip({values, List.Positions(values)}),
    AssignToSublist = (list, sublistCount) =>
        List.Transform(
            {0..sublistCount-1},
            each List.Select(list, (x) => Number.Mod(x{1}, sublistCount * 2) >= _ * 2 and Number.Mod(x{1}, sublistCount * 2) < (_ + 1) * 2)
        ),
    Result = List.Transform(AssignToSublist(IndexedList, 4), each List.Transform(_, each _{0}))
in
    Table.FromColumns(Result,columnnames)

This is the result:

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
