What Lenex is
Lenex (LEN Exchange Format) is the most widely used open data exchange standard in swimming. It was created by European Aquatics to connect meet management systems, federations and results sites, and today it is the native format of SwimRankings, Splash and timing systems such as Swiss Timing. With it, two programs exchange a whole meet without anyone typing anything.

What a Lenex file can carry
Section titled “What a Lenex file can carry”A single file carries one or more of these parts, depending on the stage of the meet:
- Meet structure (invitation): name, city, course, dates, sessions, events, age groups and rounds.
- Entries: swimmers from one or several clubs in each event, with date of birth, registration and entry time.
- Start lists: heats, lanes and times of each session.
- Results: final times, splits, reaction times, places, outcomes (DSQ, DNS, DNF) and records.
- Records and time standards: reference marks and qualifying times.
Lenex 3.0 covers individual and relay events, splits, reaction times and para swimming sport classes.
