Hi,

for one of my projects i needed to add Excel formula's to the export. so i extended the openXML write to handle this i a basic form.

i also added a builder pattern project to the solution with an extension on IEnumerable. the enables you to do something like this.

var list = new list<Project>(); list.Export().Column(Resource.ColName1, x=> x.Id) .Column(Resource.ColName2, x=> x.Description) .ToReport();
Usage
