Determining Unique Visitors Who Add to Cart and Reach Checkout

Hello,

I’m reading my store analytics and trying to understand the full picture of how many unique visitors have Added to Cart and Reached Checkout. I’m sure that many of “visitors” are actually just me when testing different things on my cart and checkout page, so I’m wondering if there is a way to check how many visitors are unique (not me) or can I possibly check the IP address of those who visited?

Thanks!
