So I wrote a little web app that allows a user to move their user data, like settings and subscribed/banned communities, from one account/instance to another.
It runs completely client-side, but is hosted on GitHub for the moment. Maybe it’ll be of some use!
Features:
- Don’t trust me or GitHub? Clone the project and host it yourself or run it locally (Example in Wiki)
 - Export user data from any Lemmy instance (>=v0.19)
 - Download user data as a text file
 - Modify user data, e.g. to add or remove followed users/communites (Example in Wiki)
- “display_name” 
 - “bio” 
 - “avatar” 
 - “banner” 
 - “matrix_id” 
 - “bot_account” 
 - “settings” 
 - “followed_communities” 
 - “saved_posts” 
 - “saved_comments” 
 - “blocked_communities” 
 - “blocked_users” 
 - “blocked_instances”
 
 - Transfer user data to the target account on the target instance
 


Sure, the code is completely client-side, simply clone it. If you’re running into CORS problems due to the file:// scheme Origin of opening a local file, simply host it as a local temporary server with something like
python -m http.server.This is due to the two ways most instances validate Cross-Origin requests:
file://URLs will result in anullorfile://Origin which can’t be authorized via the second option, therefore the need to sometimes host the application via (local) webserver.
