# Import and Export ADIF

OpsLog is **ADIF 3.1.7 compliant**: a full field dictionary, 30 promoted columns,
a generic "extra fields" editor for anything not promoted, and standard/all
export modes.

## Import

Import an `.adi` / `.adif` file into the active profile's logbook. On import,
OpsLog parses every field, maps standard fields to columns and keeps unknown but
valid ADIF fields in a per-QSO **extras** store (editable later). Country /
zones are enriched from `cty.dat` where missing. A file **without a header**
(records pasted from another log) imports fine.

- **Field remapping**: the import dialog can move a field as it reads it —
  e.g. the RSGB IOTA contest exports the island reference in `STATE`; add a
  `STATE → IOTA` row and it lands where the award looks.
- **Fill from profile**: optionally stamps your station fields *and* your
  default confirmation statuses (paper QSL, LoTW, eQSL, Club Log, HRDLog,
  QRZ.com) on QSOs the file leaves empty — a WSJT-X log carries almost none.
  Existing values are never overwritten.

## Export

- **Whole log**, **selected rows**, or the **filtered view** (no limit) — see
  [[Recent QSOs and Filters]].
- **Standard** mode exports the common promoted fields; **All** mode also
  exports every extra field; **Choose fields…** opens a picker that separates
  the official ADIF 3.1.7 fields (by category) from the OpsLog / non-standard
  tags actually present in your log, with All/None per group. Your selection is
  remembered.
- **Cabrillo** export for contest submission.

## Round-trip safety

Award references you assign manually are stored in an ADIF extra field
(`APP_OPSLOG_AWARDREFS`), so exporting your full log and re-importing it does
not lose your award-reference assignments.

## Tips

- To move a batch of QSOs between logs, export selected → import into the other
  profile.
- Use **Find duplicates** (Tools) after importing to catch overlaps.
