I'm trying to export the complete chat between a user on WhatsApp. I have tried using the "Email Chat" option, but it seems this feature does not export the complete conversation. I believe it has some sort of size limit. I experimented with several large conversations (dating back to 2 year ago) - they should definitely be 4 MB+ in file size when exported, but when I export them via Gmail, the file size is always 2 MB. The messages before that are ignored.
I also tried using web.whatsapp.com and scrolling upwards using iMacros and then selecting the text using jQuery but that is proving to be difficult. Browser crashes after a certain point.
I don't believe the database backups in
/sdcard/WhatsApp/ are of any use - they're heavily encrypted.
Any interesting work-arounds or solutions?
