Logbook import: Switch without retyping.
No need to retype your logbook: Log-K imports it from a LogTen Pro backup, the LogTen text export, an OffBlock CSV or a logbook PDF in EASA layout. A preview shows you what comes across first, and importing again creates no duplicates.
From LogTen Pro
The most complete source is the LogTen Pro backup: the .zip archive (up to 40 MB) whose file name usually starts with “LogTenProData”, or the .sqlite file inside it. It holds flights, airfields, types, registrations and people. Log-K adds the aircraft to your fleet and the people to your crew list.
Without a LogTen Pro backup, the text export “Export Flights (Tab)” as a .txt file works too. It has no record IDs, so Log-K builds stable keys from date, off-block time, route, registration and flight number, and exporting again does not create duplicates.
From OffBlock
From OffBlock, use the CSV export of your duties, a file named “Duties-….csv”. Log-K reads flights and simulator entries, your role on board and the crew you entered.
Log-K also takes the PDF export from OffBlock if it is in EASA layout. The CSV holds more detail than the PDF, though, such as the cabin crew.
From a logbook PDF in EASA layout
Log-K reads logbook PDFs in EASA layout, such as the PDF export from OffBlock: date, departure and arrival, type and registration, times, name of the PIC, landings and the columns of the right-hand page.
This is not any PDF: scans, handwritten logbooks and other layouts are not recognised. As a check, Log-K compares the sum of all rows with the printed total on the last page.
Carry forward your totals
You enter hours that are not in the file, for example from your old paper logbook, once as previous experience, in the app under Settings and in the web logbook (currently in German) under Profile. Log-K carries them forward in your statistics and your PDF export, in the iOS app as well as on the web.
Summary entries from LogTen, such as a single record “flights until 2009” without times or places, are not created as flights. The preview shows their values so you can move them into your previous experience.
What happens after the import
Before you apply anything, the preview shows what is new, what changes and which aircraft and crew members Log-K will create. For LogTen files, OffBlock CSVs and logbook PDFs, it also compares the source’s totals with Log-K’s.
Where Log-K calculates differently, night time for example, it adds a line to that flight’s remarks. Simulator entries become FSTD sessions. If you import the same file again later, Log-K creates no duplicates and does not overwrite flights you have edited since without asking.

All formats at a glance
Every format works in the iOS app on iPhone and iPad and in the web logbook (currently in German). A whole logbook goes up as a single file; rosters can go in several at once.
