It is supposed to be used via the context menu
Takes as argument the path to the Excel file.
python main.py C:\Users\User\Documents\Some excel file.xlsx
↓ file will be created
C:\Users\User\Documents\Some excel file.pdf
Please note that if the file name contains spaces, then sys.argv splits it into several arguments, which is why you have to combine all the arguments into a single string
For example, you have the following file path: C:\Users\User\Documents\Some excel file.xlsx, sys.argv will receive the following set of arguments: ["Python/Executable/File.py", "C:\Users\User\Documents\Some", "excel", "file.xlsx"], script will automaticly concatinate args with slice sys.argv[1::] and we will get full path - C:\Users\User\Documents\Some excel file.xlsx
