    Since it's a record column, I think you'd use Record.FieldNames instead.

     

    Maybe like this:

    [...]
    #"Custom items" = Table.ExpandListColumn(#"Removed Columns", "data"),
    ColumnList = Record.FieldNames(#"Custom items"{0}[data]),
    #"Expanded data" = Table.ExpandRecordColumn(#"Custom items", "data",
        ColumnList, List.Transform(ColumnList, each "data." & _))
in
    #"Expanded data"

hi AlexisOlson,

 

Is there also a possibility, if in the output table there are still several columns with records to output them also variably? Or du i have to output them step by step?

You could probably do it but it would likely be more trouble than it's worth unless you have a whole bunch of columns to expand.

    The problem is that I would like to apply the code variably to several tables. These do not always have the same headings and therefore cannot be hard-coded.
