Extract text from LSF files
To convert your LSF file to another format, you need Baldur's Gate 3 or other Game software.
To convert other file formats to the "Game Data Archive" file type, you need software like Baldur's Gate 3 or a similar tool.
The .LSF extension primarily identifies Larian Studios Files, which are proprietary compressed archives used in high-profile RPGs like Baldur's Gate 3 and Divinity: Original Sin 2. These binary files package essential game assets - including stats, character definitions, and environmental data - into a format optimized for loading speed rather than accessibility. Because they are compiled and compressed, users cannot simply double-click to view the contents; this proprietary lock-in is a major hurdle for modders who need to edit game values or extract assets. To modify these files, they must often be decompressed and converted into human-readable XML or editable LSX formats using specialized community tools like the LSLib ExportTool.
Alternatively, an .LSF file may be a LeCroy Binary Waveform generated by Teledyne LeCroy or Tektronix oscilloscopes. These files store high-precision electrical signal data that engineers cannot analyze in standard spreadsheet software. For scientific analysis, these must typically be converted to CSV for Excel or MAT for MATLAB. A third common use is for Lumion Scene Files, used by Lumion for architectural visualization.

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 LSF converter.
