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, date, boolean and string data but, of course, no diagrams, pictures, or other items.
Currently supported KNIME types are String, TimeAndDate, Double, Boolean, and Int.
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 when formula reevaluation is selected).
0means no timeout. In case it takes longer to connect to the host, the node fails to execute.
Row0and produces all integer numbers till the end. The option "Generate RowIDs (index as per sheet content, skipped rows will increment index)" generates row ids based on sheet row indices starting from
Row0, but numbers might get skipped when the row is skipped.
