Some time ago, I read a blog posting in the Mendix community that described how to
- take the first row from a spreadsheet I needed to import
- massage that row into a valid XSD file
- create and XML Schema in the Modeler from the XSD file
- use that XML Schema in a mapping document in order to create an entity
This was very useful for creating entities to import spreadsheets with a large number of columns. I have a large spreadsheet to import (several of them, actually) and can't find the blog posting. Can anyone point me to this blog posting?
