Use Python to launch Excel file

Question

when i try os.system(\"open \" + \'myfile.xlsx\')
i get the output \'0\'

similarly, trying
os.system(\"start excel.exe myfil

Answer 1

On Windows 10, this works for me:

import os
full_path_to_file = "C:\blah\blah\filename.xlsx"
os.system(full_path_to_file)

Copy-pasting any full path to a file in the command prompt (or passing it to os.system()) seems to work as long as you have permission to open the file. I suppose this only works when Excel is selected as default application for the .xlsx extention.
