SAS to CSV is a C-based converter to convert SAS7BDAT files to a CSV file. It's not very interesting, but it has a lot of utility and it's my most starred project on GitHub. I learned a lot of C and bit operations doing this project. The inspiration for this project came when a client sent us a large SAS7BDAT file that I wanted to read into R.

SAS7BDAT is a proprietary binary file format, which other programs can't read, whereas any program can read a CSV file. Currently, it only works on SAS7BDAT files generated from a specific systems. Eventually, I plan on updating it to have some 64-bit support.
