Read an Excel file
Posted to the Jython-users mailing list by Alfonso Reyes on October 14, 2007 This Jython code will open and read an existant Excel file you can download the file at http://www.nabble.com/file/p13199712/Book1.xls
To do: - create the excel file if it doesn't exist - a nicer printing method - a method to print values or formulas in the cells
1 """ read.py
2 Read an existant Excel file (Book1.xls) and show it on the screen
