Hey @Prince_Valiant We do support importing an external CSV file to your watchlist but currently only support the IMDb export format.

I'm open to supporting more formats but last time I had someone ask me about importing an export from Letterboxd and was forwarded a copy of the file, they didn't include any external ID information. Without that information (say a TMDb id), it's nearly impossible for me to build an import.

trying to grasp it exactly

So what would exactly be required to do such a thing correctly? I'm game for properly doing things.

It's nothing you can do, it's something Letterboxd would have to add to their export. They would need to add either a TMDb id or IMDb ID on each record in order for us to match it on our end.

I haven't seen an export in over a year, so it's possible their export has changed to include this but like I said, last time I saw an export it didn't include the necessary information we would need to match items on our end.

Ah! I see, well I checked and it doesn't. Maybe I can contact someone. Thanks, Travis! I'll respond if I get any headway for this.
