Text Messages

Can I download my text messages from my iPhone (from iCloud backup or any other way) onto my PC? My grandma died, and I would like to have our text message conversations on a file I can read anytime (and it will feel safer than having them on my phone, even though I pay for iCloud storage). I've paid for some services that are supposed to help with that, but they don't include photos, they don't include some messages with emojis, etc.
