It has been almost one full year since I started this project, and it has now reached a state where it is well suited for production, and intensively tested by an increasing number of people around the globe.
The most recent additions I’m the most proud of are the optimized reader and writer, that become stable in this version. It took around 6 months to get them working properly (the reader was the hardest actually), and now they’re here !
You can read and write workbooks of any size, with low and almost constant memory consumption (which is not the case with Excel actually).
I’m also really happy that people keep sending patches and asking for features, so the project continues to live, even when I’m not fully available to work on it.
You can get the latest version of openpyxl either with easy_install:
or from the official website.
