I have noticed that there seems to be a lot of posts where someone shares an LDD file and then someone else has trouble uploading directly to bricklink.
I have found a method that works pretty well and I would like to share it here. Please share your feedback and feel free to link to this topic if you find someone in the same situation.
Supertruper's Guide to retrieving parts from LDD using Rebrickable
Things you will need:
Bricklink or brickowl account
LDD file of something you want to build
Here are the steps after you have the things above.
1. Log into Rebrickable and navigate to the "My Custom Lists" section
2. On the left click "Add New List"
3. (Optional) rename your list using the "Edit List Details" button
4. Click "Import Parts" and browse or drag your LDD file
5. Click "Append Parts"
From here the parts list will load but there will be color errors and Minifig parts do not come up correctly.
There will also be no prints selected. Any printed parts will need to be updated.
6. Once all the parts are adjusted click "Buy Parts" from here you can add them to your Bricklink or Brickowl account
