Hi Irene, With that explanation, the performance makes sense. This is certainly an edge case. Unfortunately the spreadsheets are provided by a large automation vendor and are a standard part of their documentation. IMHO, it's rather irresponsible to publish them without proper column headers but that's just me.
I'll find a way to pre-process them using other applications that replace missing column headers with a placeholder (KNIME Is the best candidate).
