Features and technical overview
Import data to spreadsheets
LoadFromDictionaries
We have added a new method - LoadFromDictionaries - that enables importing dynamic objects into spreadsheets.
Here is a tutorial that shows how this works.
LoadFromCollection with attributes
We have also improved the LoadFromCollection method and added a set of attributes for adding calculated columns, define order of the class members, ignoring members, set totals row, autofit columns, etc.
See this tutorial in our developer wiki.
