Hi,
In my json input file I have a very large column (data_found in my request) and it is very long to load data in PowerBI.
I just want an extract of this large columns (the first 100 characters for example).
In the advanced editor, is it possible to add M language instructions to do that ?
Thanks
Dominique
let
Source = Json.Document(File.Contents("C:\carto\results.json")),
phone = Source[phone_number],
columns = phone[columns],
#"Converted to Table" = Table.FromList(columns, Splitter.SplitByNothing(), 1, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"location", "numbers_of_rows_analyzed", "percentage_of_personnal_data", "data_found"}, {"location", "numbers_of_rows_analyzed", "percentage_of_personnal_data", "data_found"}),
#"Changed Type" = Table.TransformColumnTypes(#"Expanded Column1",{{"data_found", type text}})
in
#"Changed Type"
Solved! Go to Solution.
No need for the Advanced Editor.
Select your column - on the "Transform" tab: Extract - First Characters - 100 - OK.
