I don't have any examples but there are overloads of the Export method that take a worksheet so you could easily have each grid export to a different worksheet in the same workbook. In theory you could have multiple grids on the same worksheet using the overload that takes the worksheet and starting row/column but you would have to know how many rows of data were used in the excel output of the previous grid. I think the only way to know that would be to do a foreach to access the allocated rows in the worksheet and look for the highest Index.
