Pinterest by default does not let you download images or videos. Inspecting the source and then downloading images can be a major pain. This extension will pick out all the images and videos in a pin and let you save them to your computer.
The almost complete lack of comments shows that Pinterest is no longer enthusiastically supported by its users. It's not possible to export data.
If this product could connect to Notion or Airtable and import all data there, instead of exporting videos and images individually, I'm sure there would be a lot of upvotes.
