Following the questions:
- Javascript or Flash export to CSV/Excel
- Is it possible to use any HTML5 fanciness to export local storage to Excel?
and as suggested, I'm thinking about generating a CSV file content in the client and then use a Data URI to prompt an "open-in-Excel" action from the browser. After reading the limitations and different levels of support of this feature (Data URI) from browsers I'd like to know about first-hand experience of this technique and about things I've to take care of.
Thx.
