A sas7bdat file reader for Python
Project description
sas7bdat.py
This module will read sas7bdat files using pure Python (2.6+, 3+). No SAS software required! The module started out as a port of the R script of the same name found here: <https://github.com/BioStatMatt/sas7bdat> but has since been completely rewritten.
Also included with this library is a simple command line script, sas7bdat_to_csv, which converts sas7bdat files to csv files. It will also print out header information and meta data using the –header option and it will batch convert files as well. Use the –help option for more information.
As is, I’ve successfully tested the script almost three hundred sample files I found on the internet. For the most part, it works well. We can now read compressed files!
I’m sure there are more issues that I haven’t come across yet. Please let me know if you come across a data file that isn’t supported and I’ll see if I can add support for the file.
Usage
To create a sas7bdat object, simply pass the constructor a file path. The object is iterable so you can read the contents like this:
from sas7bdat import SAS7BDAT
with SAS7BDAT('foo.sas7bdat') as f:
for row in f:
print row
The values in each row will be a string, float, datetime.date, datetime.datetime, or datetime.time instance.
If you’d like to get a pandas DataFrame, use the to_data_frame method:
df = f.to_data_frame()
