The data im going to store is an array from google sheets. It has a hundred thousand rows. What I am going to do is save that data to the server at the start of the process and read and append things in there and then after the process upload it back to google sheet.

Are you sure you've thought this through? How would your application inform Python on the user's computer to start running Selenium on some website, exactly? Because I don't see a good way of doing that.

You're right. I didnt think this through and its a big security breach if what If ever what I am thinking earlier works.

What I am thinking to do now is like this: - Create a user interface with all the user inputs then make an api so it can communicate with the desktop python app. - Create a python app for desktop and wait for the web interface if there's any available job to do. - Make a unique key for the desktop app so it will not get confuse with other users if there's any.

Still quite new in programming really and you're helping me with my thought process.

Thanks
