The first step, is to convert the excel file to the ARFF format file, but i don't really know how to do that. I saw that the StringToWordVector class will be usefull to continue with the process, but before that i need the ARFF file. Load CSV Files in the ARFF-Viewer. Open your CSV file in the ARFF-Viewer by clicking the “File” menu and select “Open”. Navigate to your current working directory. Change the “Files of Type:” filter to “CSV data files (*.csv)”. Select your file and click the “Open” button.
Is there any possibility to transform an Excel file into an ARFF file? Save it as a CSV (comma-separated values) file with the '.csv' extension and then load it into the Weka Explorer.

From there you can save it then as ARFF file. You can also use the weka.core.converters.CSVLoader from command line, here's an example: HTH Cheers, Peter - Peter Reutemann, Dept. Of Computer Science, University of Waikato, NZ +64 (7) 838-4466 Ext. 5174 Wekalist mailing list.
