Import your dives

Import UDDF dives

UDDF (Universal Dive Data Format) is the closest thing dive logging has to a lingua franca — if your current software can export at all, it can probably export this. Import is free, with a preview before anything is saved.

Getting the file

Look for Export in your current app and choose UDDF:

Subsurface: File → Export… → UDDF (or see the Subsurface guide — its native file works too).
Diving Log, MacDive, and most desktop loggers: an Export or Backup menu with a UDDF option.
Files ending .uddf or .xml both work.

Importing it here

Create a free logbook (or sign in) — importing is free on every plan, always.
Open Import & export from the account menu and drop your file on the import panel.
Review the preview — every dive is shown exactly as it will be saved, and nothing is written to your logbook until you confirm.

What carries over

Dates and times, maximum depths, durations, water temperatures, dive sites, buddies, notes, and depth profiles where the file carries samples. UDDF files vary by exporter; the preview shows exactly what was read before you commit anything.

After import your dives behave like any others: unit preferences apply, stats include them, and each one can become a shareable public page. Also importing from elsewhere? All the formats: Subsurface, CSV, Excel, DAN DL7.
