windows automation software - Automated data entry

I need some tool to run on my windows PC. The pc uses a mobile hotspot 4g usb connection. SUMMARY: I have people that call me and provide their information. The data is 100+ people per day. They provide name email phone etc to me and I put it in a file. I need a tool that will put this data automatically into a specified website because it takes too long to do it manually. Also it has be unique each time because I am unable to submit over and over again so theres a simple process of clearing cookies/cache,refreshing ip, and reloading the website. I Need a custom windows tool that will be able to do all of these tasks. Tool will need to work together with other tools or stand-alone to be able to perform the following tasks: -clear browser cookies/cache -connect to internet/refresh IP -use new browser/user agent randomizer and open web browser and go to URL -obtain data from file - enter data from given file ---in website fields enter , name, email into website, and submit. -disconnect from internet -repeat these steps with next data field in file
