Analyze old data

Analyze old data

I have the following excel sheets:

- People asking for materials
- People asking questions
- People asking for a guided tour
- People which ended up signing up for courses - and which courses they signed up for

All persons would be identifiable either by phone number og e-mail.

I would like to import all this data into Zoho CRM, so I could do a little analysis - and compare to whatever I put into Zoho CRM from now on. Is that even doable (like they all were in different places of a sales funnel) to get it into Zoho in any structured way?
