Parso is a lightweight Java library designed to read SAS7BDAT datasets. The Parso interfaces are analogous to libraries designed to read table-storing files, for example, CSVReader library. Despite its small size, the Parso library is the only full-featured open-source solution to process SAS7BDAT datasets, both uncompressed, CHAR-compressed and BIN-compressed. It is effective in processing clinical and statistical data often stored in SAS7BDAT format. Parso allows converting data into CSV format.
