After two weeks of intense activity around openpyxl, I’m releasing version 1.1 today. This new version brings support for dates and number formats.
Thanks guys for boosting my morale, providing valuable advises and patches !
Many thanks goes to Marko Loparic for his support and enthusiasm 😉
You can get the sources for the latest version here http://bitbucket.org/ericgazoni/openpyxl. I expect a lot of bug reports with this new version, as it is stable but not extensively tested yet, and that the number of possibilities have seriously increased with the introduction of number formatting.
Keep in mind that the memory footprint is still high, but that it is the target for milestone 1.2. It should perform reasonably well if your needs are moderate (<100.000 cells), but if you want to add more data, then it might start consuming RAM pretty quickly. This holds for writing and reading.
Memory consumption is almost linear, and a 15MB workbook results in 450MB in RAM.
There is also a new mailing list for the project: http://groups.google.com/group/openpyxl-users. It’s pretty empty for now, but feel free to ask questions there, I’ll be reading it regularly.
Bug reports will be better handled if they are filed on the project bug tracker: http://bitbucket.org/ericgazoni/openpyxl/issues/new.
Happy coding !
