Exporting a WhatsApp chat can be easily done from your Android or iOS device. It is done on a chat basis, so if you want to export several chats you will have to export them individually. When exporting, make sure to select the chats Without Media option. Once generated, you can send it via mail, so you can save it in your computer.
The export on Android might include several files. We are only interested in the text file (i.e. txt extension file).
For more details, refer to official website.
The chat is exported as a zip, which can be easily unzipped in your computer.
