sas2parquet

The ultimate SAS (.sas7bdat) to Parquet converter — built to handle files that fail with standard tools.

sas2parquet automatically detects encodings, repairs schemas, infers correct data types, and performs pixel-perfect validation between SAS and Parquet outputs.

✨ Features

🚀 Quick Start

Install

pip install sas2parquet

✅ Usage

Convert a directory (recommended)

sas2parquet path/to/sasdata/

• Converts all .sas7bdat files recursively

Output (default):

path/to/file.parquet
