Automate the process of working with sites

I go to different websites every day on the same CMS. I collect statistics from the necessary pages, make some calculations and save all data in a .xlsx file. Next, I send the file to another system where it is necessary to log in as well and it gives me general statistics in a convenient form for me. I spend a lot of time on this and I have the idea to automate it.

I will give you access to one of the sites and an example of .xlsx file, as well as a link to the service where to download .xlsx file. I would like to hear from you the timing of the implementation of automation of this routine work and the cost.

This can be both a desktop application for a computer, and an Android application for a phone, and a script in PHP. It doesn’t matter to me, it’s important to work and do what I need quickly and automatically.
