This node reads Excel files (xlsx, xlsm, xlsb, and xls format). It can read a single or multiple files at the
same time, however reading only
one sheet per file. The supported Excel types that can be read in are string, number, boolean, date, and time
but not pictures, diagrams, etc. Formulas can also be read in and reevaluated if desired.
The data is read in and converted to the KNIME types string, integer, long, double, boolean, local date, local time, and local date&time. Upon execution, the node will scan the input file to determine number and types of the columns and output a table with the auto-guessed structure and KNIME types.
The performance of this node is limited (due to the underlying library of the Apache POI project). Reading large files takes a long time and uses a lot of memory (especially files in xlsx format when formula reevaluation is enabled).
The dialog of this node shows a preview and the file content. While the preview shows the table that will be read in having the settings applied and is updated once a setting is changed, the file content shows the content of the file as it is displayed in Excel. This allows finding row numbers and column names easier to specify different settings.
