hi there,
Every month I get a brunch of 20 xls files containing 12+ columns. The name of those columns changed every month (typically previous 5 months, current month, next 6 months ) . How can I use the Table.ExpandTableColumn function without knowing the names of the columns ?
I tried Table.ExpanTableColumn(#"PreviousStep", "XlsContent",{*}) and, of course, it didn't work 🙂
I guess I should get them from a function, but I can't figure out wich one.
Can you help ?
thanks !

Hi @fsim
Please, see the attached file with a solution, it will look at all the column names within the tables and use this as a list to expand columns
Hello @fsim
use this codesnippet to understand how to build your Table.ExpandColumn dynamically.
ExpandAllColumns = Table.ExpandTableColumn
(
PreviousStep,
"ColumnToBeExpanded",
List.Union
(
List.Transform
(
List.Buffer(PreviousStep[ColumnToBeExpanded]), each Table.ColumnNames
(
_
)
)
)
)
in
ExpandAllColumns
