How to import your Letterboxd data into CineFR

You can move your Letterboxd history to CineFR in a few minutes. The ZIP file Letterboxd gives you works as it is, so there's nothing to convert.

Step by step

On letterboxd.com, open Settings, go to the Data tab (letterboxd.com/settings/data) and choose Export your data. A ZIP file downloads.
Sign in at cinefr.com. Importing currently works in the browser, on a computer or on your phone.
Open Settings → Import from other platforms and choose the ZIP file.
CineFR shows what it found: titles for your Watched list, titles for your Watchlist, ones already in your lists and any it couldn't match. Tap Add to finish.

Watched films from your diary, watched list and ratings, with the date you logged them.
Your watchlist.
Not included: star ratings and review text. Titles move, scores and words don't.

The file itself isn't uploaded. Titles are looked up on TMDB and only the matches are saved to your account.
Titles that can't be matched are listed at the end so you can add them with search.
Accounts have a storage limit. Very large histories are imported partially, newest titles first.
If your browser can't open ZIP files, unzip it first and upload the CSV files inside.
