a while back we had a bug that dealt with empty rows in excel spreadsheets. ya’ll provided a fix for that by creating a new method off PdfSaveOptions.getCellsOptions() called setSkipEmptyRowsAndColumns().
in the latest groupdocs-conversion the PdfSaveOptions does not have a getCellsOptions() method defined on it and i can’t seem to locate where the setSkipEmptyRowsAndColumns() call has gone.
