Strange behavior of Excel Reader

I’m reading Excel-Files of changing structure in a loop.

After the second read the “Replace Header” Node fails if I do not dump the data to a csv and reread it.
The “Support for changing schemas” option is checked in the reader’s config

Hello @fschmid,

can you give us a bit more information? For example what error are you getting? What are you doing with data from Excel files eventually? You create same headers and concatenate? Also what KNIME version are you using?
