Is there any way to Map all or any of my Zoho CRM leads

I have 800+ leads in my Zoho CRM account and I will eventually have to visit most if not all of these at some point. Therefore, mapping my travel route efficiently and effectively is very important. I am unable to locate a function within Zoho that gives me this capability. Is there any software out there that will give me the capability of mapping my leads list if I were to upload them in a .csv or .xls file?
