In this corrected command, we pass the command and all its arguments as a single list. This approach ensures that everything is included and executed in one go.
Changing Directory Properly
Additionally, to manage the working directory in a more effective manner, consider using Python’s built-in os module to change directories:

This step changes the current working directory to libreoffice_path before executing the LibreOffice command. It ensures that the script has access to the necessary files without encountering path issues.
Conclusion
By following these guidelines, you can successfully convert files to PDF using LibreOffice from within your Python scripts without encountering the pesky Access Denied error. Remember to adjust the subprocess.run() command and utilize os.chdir() for managing your working directory more effectively. With these tips, your file conversion tasks will become smoother and hassle-free!
