put an xml and csv file togehter

okay. thx.

The Workflow is already very good. But some specials make that workflow better.
The Final file is a XLSX-Sheet. But if i Have more than 1,5 m rows than excel cannot create a file. I must take a CSV-Writer. Does Knime have a Node with a IF-Decision of Count-Rows ?
For Example:

Below 1 000 000 rows do a XLS-Write and Above 1 000 000 write in CSV ?
