This node reads a spread sheet and provides it at its output port.
It reads only data from one sheet at the moment. It can read only numeric data (or strings) but, of course, no diagrams, pictures, or other items.
Currently supported KNIME types are String, Double, and Int. (Time or date in the spread sheet is represented as String and can be translated into the appropriate TimeAndDateCells with the corresponding nodes.)
It reads in the data from the sheet and sets a type for all columns that is compatible with the data in that column (in the worst case "String" covers all).
The performance of the reader node is limited (due to the underlying library of the Apache POI project). Reading large files takes a very long time and uses a lot of memory (especially files in xlsx format).
