Commonly used EPPlus functions to push data to spreadsheet

The basic syntax to apply a value to a cell:
WorksheetName.Cells(row#, column#).Value = “data to be applied”
Here is a simple example:
dim sTitleName as string = "Formula Code \ Version: " & _objectkey
		sheet1.Cells(2, 1).Value = sTitleName
		sheet1.Cells(3, 1).Value =  ObjProperty("DESCRIPTION").
You can use variables for the row and column numbers, which can be helpful in case you need to later insert rows in the spreadsheet, or if the exact address is variable:
		sheet1.Cells(headerrow, 1).Value = sTitleName
		sheet1.Cells(headerrow + 1, 1).Value =  ObjProperty("DESCRIPTION")
Example getting table data and applying it to variable rows:
'Ingredient Table
		dim ingrstartrow as integer = headerrow + 4
		dim itemcol as integer = 1
		dim fmlcol as integer = 2
		dim desccol as integer = 3
		dim qtycol as integer = 4
		dim uomcol as integer = 5
		dim instruccol as integer = 6

		'Column Headers
			Sheet1.Cells(ingrstartrow, itemcol).Value = "RM Code"
			Sheet1.Cells(ingrstartrow, fmlcol).Value = "SubFmla Code"
			Sheet1.Cells(ingrstartrow, desccol).Value = "Description"
			Sheet1.Cells(ingrstartrow, qtycol).Value = "Quantity"
			Sheet1.Cells(ingrstartrow, uomcol).Value = "UOM"
			Sheet1.Cells(ingrstartrow, instruccol).Value = "Instructions"

		'Data table
		dim itemrow as integer = ingrstartrow + 1
		for x as integer = 0 to oLines.length-1
			Sheet1.Cells(itemrow, itemcol).Value = oItems(x)
			Sheet1.Cells(itemrow, fmlcol).Value = oFmla(x)
			Sheet1.Cells(itemrow, desccol).Value = oDes(x)
			Sheet1.Cells(itemrow, qtycol).Value = math.Round(cdbl(oQty(x)), 4)
			Sheet1.Cells(itemrow, uomcol).Value = oUOM(x)
			Sheet1.Cells(itemrow, instruccol).Value = oInstruc(x)

			itemrow = itemrow + 1

If your report requires list labels (enum lists, status, etc.), you may prefer to generate and use XML data for the objects, which provides _LABEL fields for list-supported data, _FORMATTED fields for parameter values, etc. Regardless of how you retrieve and modify the data, setting it to cells is the same.
