How do I save a data table row in a excel column?

Hello all,

I have a data table wich will be filled with entries of a webform.
One entry is one row in the data table.
Later I want to extract the data table into an excel file, but I want to save the data from the table not in the same format.
The entries in the row should be saved as entries in a columns.
So the entries should switch from horizontal to vertical.
Therefore it also needs to add the columns to the excel file.
Can anyone help me with that?

Thank you!
