Calvin,
On further investigation, what was happening is that the TopLevelGroup Caption was getting exported to excel, along with the "header" above the caption. When I imported the file back into the grouping control, those 4 rows were data rows in the grid, instead of going back to the caption and header. I will check out your sample. Thanks!

>Martin, please find the attached sample in which I have copied the GroupingGridExcelConverter.cs and made some changes for your mentioned requirement. You can modify the class as per the requirement. The current version of excel converter only imports the content in the Excel spreadsheet without the styles and other formatting in MS Excel. We are working on improving the importing functionality and the grid importer would support importing with styles and other features in our coming release.
