Hello,

I have an excel spreadsheet with a list of thousands name, last name ans mail address. These people have left their company and I am supposed to update the information on salesforce.
the process is:

- search the contact
- edit contact
- click on has left the company
- save
Repeat.

Does anyone has a code that does that?
Or can anyone, tell me what/how can I learn to implement that?
I usually code in VBA and I have some notions in Python.
It's the first time I try to implement a code on a website and I'm a bit lost.
I just learned HTML5 so now I can understand how the page is written. But I  don't know how to send a request and interact with the webpage.
Also I read about API, I think I understand what they're used for, but not how to use them.

Thank you for your help, I really need that.
