Changing a column with an unknown type (?) into a double

KNIME Analytics Platform

Hi all,

I am running into problems when I import my XLS file. And the file contains a couple of columns that may be empty or may be filled in with a double. And I need to do check on that column. So I get an error when the column is empty and I want to check if the format of the double is correct.

So my question is if there is a way to force or change the column type from unknown(?) into a double?

hello!

 

Yes! You can do it easily with for example Column Rename node.
