# pandas.read_sas

pandas.read_sas(filepath_or_buffer, *, format=None, index=None, encoding=None, chunksize=None, iterator=False, compression='infer')

  Read SAS files stored as either XPORT or SAS7BDAT format files.

  The file format is inferred from the file extension if not explicitly specified. Supports both full reads and chunked iteration.

  Parameters:
    filepath_or_buffer str, path object, or file-like object

      String, path object (implementing `os.PathLike[str]`), or file-like object implementing a binary `read()` function. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: `file://localhost/path/to/table.sas7bdat`.

    format str {‘xport’, ‘sas7bdat’} or None

      If None, file format is inferred from file extension. If ‘xport’ or ‘sas7bdat’, uses the corresponding format.

    index identifier of index column, defaults to None

      Identifier of column that should be used as index of the DataFrame.

    encoding str, default is None

      Encoding for text data. If None, text data are stored as raw bytes.

    chunksize int

      Read file chunksize lines at a time, returns iterator.

    iterator bool, defaults to False

      If True, returns an iterator for reading the file incrementally.

    compression str or dict, default ‘infer’

      For on-the-fly decompression of on-disk data. If ‘infer’ and ‘filepath_or_buffer’ is path-like, then detect compression from the following extensions: ‘.gz’, ‘.bz2’, ‘.zip’, ‘.xz’, ‘.zst’, ‘.tar’, ‘.tar.gz’, ‘.tar.xz’ or ‘.tar.bz2’ (otherwise no compression). Set to `None` for no decompression. Can also be a dict with key `'method'` set to one of {`'zip'`, `'gzip'`, `'bz2'`, `'zstd'`, `'xz'`, `'tar'`} and other key-value pairs are forwarded to `zipfile.ZipFile`, `gzip.GzipFile`, `bz2.BZ2File`, `zstandard.ZstdCompressor`, `lzma.LZMAFile` or `tarfile.TarFile`, respectively. As an example, the following could be passed for faster compression and to create a reproducible gzip archive: `compression={'method': 'gzip', 'compresslevel': 1, 'mtime': 1}`.

  Returns:
    DataFrame, SAS7BDATReader, or XportReader

      DataFrame if iterator=False and chunksize=None, else SAS7BDATReader or XportReader, file format is inferred from file extension.
