How do I open / read password protected xls or xlsx (Excel) file using python in Linux?
You can use the openpyxl Python Library to operate with (and open) Excel files. I don believe opening a Excel file that has a password is supported in OpenPyxl. That is you can open the file! However this sounds in contradiction to what you can do in openpyxl. You can apparently set the password. This implies you can then subsequently open the file using the passoword you just created. Here is some code to help. The 3rd line is setting the password. So the code below would need to be modified. And I have only used Python on Windows systems not Linux. import openpyxl code wb = ('') code = 'thepassword' code
