About L files
The .l file extension is most commonly associated with either an ActivInspire Resource Pack or a Lexical Analyzer Source file. In educational environments, Promethean ActivInspire uses .l files to distribute compressed interactive whiteboard resources, such as images, templates, and interactive lessons. For software developers, .l files contain source code used by the Lex or Flex scanner generators to output C source code for lexical analyzers.
These formats come with distinct real-world disadvantages. As an educational resource pack, the .l format is proprietary and acts like a closed archive. It requires heavy, specialized whiteboard application software to open and is natively unsupported on web browsers or mobile devices. As a Lex file, it requires a compiler, a development environment, and command-line knowledge to actually process.
If you are dealing with an educational resource pack, extracting or converting it to ZIP is the best workaround to access the underlying images, sounds, and media assets. If it is a Lex file, it is best viewed as TXT or compiled directly to C.
Because .l represents multiple entirely distinct file types, traditional online converters often fail or return unexpected errors. Just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. If our analysis detects standard text or a supported embedded compressed archive, viewing or extraction is easy.
If you want to convert L file to GAL, CM3, G, KL, DL, MP3, WAV, AAC, FLAC, OGG, WMA or M4A, you can use Promethean ActivInspire or similar software from the "Resource Pack & Source Code" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to L, try Promethean ActivInspire or another comparable tool in the "Resource Pack & Source Code" category.
The L Converter Story
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 L converter.
