Log4OM: export and import ADIF
Log4OM exports and imports ADIF from its File menu. Drop the file below to check it before it goes into Log4OM — or after it comes out — and save a clean ADIF.
Export from Log4OM
File → Export ADIF writes the whole logbook. Tick Export as standard ADIF to leave out Log4OM’s own fields, or Export selected fields to choose them.
Import into Log4OM
File → Import ADIF, then Load and choose the file. The import window can apply quality-check corrections to the DXCC data, treat QSOs a few seconds apart as the same one (Duplicates threshold), and drop the current database before loading — leave that one unticked unless you mean to replace your log.
Before importing
Files from other programs can trip an import. Check the file here first: the page lists what does not follow the ADIF specification and fixes what has a single right answer — bands, dates and times, submodes like FT4 — then saves an ADIF 3.1.8 file. To put several logs into one first, use Merge ADIF.
What is tested — and what is not
The menu names are from the Log4OM 2 user guide (June 2025). We did not run Log4OM: whether it takes a particular file is up to Log4OM.
Questions
- Is the file uploaded?
- No. It is read and fixed in your browser; nothing is sent anywhere.
