Hi Team,
I am new to Power BI and stuck in converting my server data into tables.
I got a response from server as below
------------
Column1
------------
List
List
List
List
I want to make new table with each of the these lists to seperate columns.
The number of lists are dynamic per grid.
Please anyone help me with the pq code
Solved! Go to Solution.
Hi @SVUser123
I create a sample to have a test.
Sample:
My Code:
let
Source = #table({"1", "2","3"}, {{ {1,2}, {3,4},{4,5} }}),
#"Unpivoted Columns" = Table.UnpivotOtherColumns(Source, {}, "Attribute", "Value"),
#"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"}),
#"Added Index" = Table.AddIndexColumn(#"Removed Columns", "Index", 1, 1, Int64.Type),
#"Reordered Columns" = Table.ReorderColumns(#"Added Index",{"Index", "Value"}),
#"Pivoted Column" = Table.Pivot(Table.TransformColumnTypes(#"Reordered Columns", {{"Index", type text}}, "en-US"), List.Distinct(Table.TransformColumnTypes(#"Reordered Columns", {{"Index", type text}}, "en-US")[Index]), "Index", "Value"),
#"Merged Columns" = Table.CombineColumns(#"Pivoted Column",{"1", "2","3"}, each List.Transform(List.Zip(_), each Record.FromList(_,{"1","2","3"})),"Merged"),
#"Expanded Merged" = Table.ExpandListColumn(#"Merged Columns", "Merged"),
#"Expanded Merged1" = Table.ExpandRecordColumn(#"Expanded Merged", "Merged", {"1", "2","3"}, {"1", "2", "3"})
in
#"Expanded Merged1"
You can copy and update my code steps after #"Removed Columns". You need to add an Index for your lists and these numbers will be column headers after you pivot the list column. Here I have three lists in one column, so I create an Index from 1 to 3. Then merge and expand merge by M query.
Result is as below.

I did try to use the Split function as
Table.SplitColumn(reqTable, "Column1", Splitter.SplitTextByDelimiter(","))
but got an error saying "We cannot conver a value of type List to type Text"
