It worked for me ! Thanks a ton !

For all the have a error.
It is maybe because you don't have Whatsapp on english. But there is a easy fix. Just go to Row :19, :24 and translate the "You" in your language.

document.querySelectorAll('span[title=You]')[0]?

Hope this help somebody

Any help for this error

its work for me thanks

Great tool. All functions work smoothly except for one.

I purchased the paid Chrome extension and a bug with the Export All Groups (beta) function has given me a headache. It dies when two or more WhatsApp groups have the same name.

It seems it also dies when a group name from another WhatsApp account is duplicated. I mean, I was extracting contacts from more than 30 phones and when Phone-1-Group-X was extracted, it remanined in cache. So when I tried to extract all groups from Phone-2, including a group called Group-X, it died again no matter that group name was not duplicated within Phone-2. In other words, the problem seems to be with cached data.

In order to bypass the problem, you have to:

1. Rename or delete the repeated groups
2. Logout from WhatsApp web
3. Clear your browser's cache
4. Restart your browser
5. Log in back to WhatsApp web

Fix that and let's go for a beer.

@iabarragan Unfortunately, I'm not able to reproduce the issue by following the same steps. I can export duplicate named groups quite fine. Drop me an email on shaneapen@gmail.com and let's try to sort that out.
