Convert SAS or audio files (SD2) online for free
The converter easily converts your SD2 files to various formats - free and online. No SAS or or other Data software needed.
To convert other file formats to the "Statistical Data File" file type, you need software like SAS or a similar tool.
The .sd2 file is a multi-purpose extension primarily used as a SAS Version 6 Dataset by SAS software for statistical data storage. It is also utilized by Cedrus SuperLab for psychological experiment logs, and historically by Avid Technology for Sound Designer II audio files on classic Mac OS systems. You can read the data variants using SAS or modern data science libraries like Python's Pandas. The audio variant was native to early digital audio workstations like Pro Tools.
These formats present severe operational challenges today. The SAS V6 dataset is a proprietary, legacy format from the 1990s. Opening it natively typically requires an expensive commercial software license, severely limiting data portability. The Sound Designer II audio format is notoriously fragile: it relies on the deprecated Mac OS 'resource fork' to store its header information, including sample rate and bit depth. If you copy an audio .sd2 file to a Windows PC or modern macOS system without zipping it first on the original hardware, the header is stripped. This leaves raw, unplayable PCM data that requires manual hex editing or guesswork to recover.
To bypass these limitations, you must convert the files to modern, open standards. For the dataset version, convert to CSV or XLSX for universal accessibility in Excel, R, or Python. For the legacy audio format, convert to WAV or FLAC to ensure long-term, lossless archiving without the need for resource forks.

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 SD2 converter.
