Hello riddhisanghoi,
we have removed this option from the new Excel Writer for two main reasons. The writer can now write to many different file systems including remote where we can not open the file with your local running Excel program. In addition the option would not work when the workflow is executed on the KNIME Server where KNIME is executed without a user interface.
For which use case do you need this option? Would it be also ok if we provide you with a Component on the KNIME Hub that you can drag & drop onto your workflow that uses a Java Snippet node that would open Excel once the file has been written?
Bye
Tobias
