QuoteOriginally posted by: mtsmhi, thank you for pointing this out. I am not getting a very good sense of what this can do. You seem to be saying that it is a technology demo project. I think that I need something operational fast.Short answer: it isn't intended for production use.Long answer: We are using a subset of the expy functionality in a larger project very successfully. I've split off expy from the larger project and expanded it a little bit so that expy is useful on its own, but, as I wrote, primarily as a hands-on example how one can efficiently integrate excel and python. At the present it is not intended for "production" use. Perhaps if there is sufficient interest we will make it so, but for the present it is likely to evolve only as the larger project evolves.What are you trying to do? The first thing to make sure is that your Python code is all done and working -- integrating with Excel should be the easy part!
