Extract text from LENEX data files (LEF)
To convert LEF data files to another format, you need Swiss Timing or other Data software.
To convert other file formats to the "LENEX Exchange Format" file type, you need software like Swiss Timing or a similar tool.
A .LEF file most commonly acts as a LENEX Data Exchange file, heavily utilized by swimming competition software to store meet data, athlete times, and event results. These are generally stored in an underlying XML structure. The extension is also utilized for entirely unrelated purposes: Samsung Anycall PC Manager uses it for proprietary phonebook backups, court reporting software like YesLaw uses it for Litigation E-Transcripts, and Cadence Design Systems employs it as a Library Exchange Format for integrated circuit (IC) physical layout abstracts.
The primary disadvantage of the .LEF format is its extreme specialization and lack of native support. These files are typically locked into proprietary ecosystems. You cannot natively view a LENEX file in a web browser, and opening a YesLaw E-Transcript requires specific legal software. Samsung's phonebook backups are effectively obsolete, making the retrieval of contact data extremely frustrating without the exact vintage software.
Converting .LEF files usually involves extracting the readable data. Because most modern .LEF files (like LENEX and E-Transcripts) rely on XML, the best conversion targets are XML, CSV, or plain TXT. Converting to these formats makes the data accessible in standard applications like Microsoft Excel or text editors, though specialized software-specific bindings and formatting will be lost.
Because these formats serve highly restricted, niche industries - ranging from professional swim timing to microchip design - standard online converters fail completely. They lack the parsers required to interpret the legal or athletic schemas. Often, only the original software can properly read or export the data.
Convert.Guru analyzes your LEF file, detects the exact format, and lets you read the text inside.
Users also converted LXF, XMEF, SBF, IRF, SIG, PLAN, PDF, TXT, LRF, ZIP, WEBARCHIVE, CDW and RPMSG files.
If you want to convert LEF file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Swiss Timing or similar software from the "Swimming Competition Data Exchange" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to LEF, try Swiss Timing or another comparable tool in the "Swimming Competition Data Exchange" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our LEF converter.
