Today, I found a phone I thought I had lost a few years ago (an iPhone 5s).
I was wondering if I could extract the saved WhatsApp conversations from the iPhone to my PC and be able to read them?
I don't have the same phone number anymore, so I don't know if I could use another number and restore my chats.
Is there any way to extract those threads and read them? As it turns out, I also have them Backed up in iCloud, if that helps.

Introduction
The problem lies with the fact that WhatsApp does not store a history of your chats on its servers (except undelivered ones). That means that unlike other messaging providers, WhatsApp cannot simply repopulate your chat history on every device because there is no central location (server) that stores them for you. While this is a great step towards privatizing your chats, this makes things all the more difficult for your case.

Conclusion
Based on the (limited) options available to you, I'd recommend trying the second one first as you will have the greatest chance of actually reading the messages, compared to option one and three. Please read through this guide to learn how to restore your chat history. I am interested if it works for you. Let me know how you get on.
