Part 1: How to Forward Your Android WhatsApp Chats to Your Email as Text File
You can also send Android WhatsApp text messages to your email address as .txt file and later download the .txt file on your iPhone 8 or iPhone X. To do so, you’ll have to follow these steps:
Step 1: Open WhatsApp on your Android phone, and go to the settings section. You should then go to the chats section, and click on ‘Chat History’.

Step 2: You should see a drop down list, and one of the options there is ‘Email Chat’. Select that one.

Step 3: Now you have to choose the conversation in WhatsApp that you would like to keep. When you’ve done that, a little pop up will appear telling you that ‘attaching media will generate a larger email message’.

Step 4: Click on either ‘Without media’ or ‘Attach media’, depending on how important it is to you that you keep all of the images that are in that WhatsApp conversation.

Step 5: Now you have to put in the email address that you would like to send the email to. Then tap the ‘Send’ button.

Step 6: Now put your old Android phone down, and open up your new iPhone 8 or iPhone 8 Plus. Open up your email app, and wait for the email to come through. This may take a long time if the email is very large.
Step 7: Finally, tap on the .txt file attachment and download the text file with the WhatsApp chats on your iPhone.
This method is little time consuming because you’ll need to compose multiple mails if you want to forward all the chats to your email address. Another disadvantage of this method is that the chats won’t appear on iPhone’s WhatsApp Messenger app.
