Hi @Anonymous ,

Basically you can refer this power query code:

let
    
    Source = {
            [Name="A",Age=null],
            [Name="B",Age=20],
            [Name="C",Age=16]

 

        },
    #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    Custom1 = Table.ToRecords(Table.SelectRows( Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"Name", "Age"}, {"Column1.Name", "Column1.Age"}),each [Column1.Age]<>null)),
    #"Converted to Table1" = Table.FromList(Custom1, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
    #"Converted to Table1"

Here is the sample file that hopes to help you: record.pbix

One option is to expand the record and then filter on the expanded values.  If you want to do it while it is in Record form, you can do it like this.

Add a Filter step to any column (to get the basic syntax) and then update it in the Formula bar to get something like this

= Table.SelectRows(#"Added Custom", each (Record.Field([RecordColumn], "RecordField") <> null))

Where #"Added Custom" is your previous step [RecordColumn] is your column with the Records in it, and "RecordField" is the field within the Record that you are checking if it is null or not.

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
