Aspose.Cells - Formula Calculation Engine
The formula calculation engine is embedded in Aspose.Cells. It can not only re-calculate the formula imported from a designer spreadsheet file but also supports to calculate the results of formulas added at runtime.
C#
//Instantiating a Workbook object
Workbook book = new Workbook();
//Obtaining the reference of the newly added worksheet
int sheetIndex = book.Worksheets.Add();
Worksheet worksheet = book.Worksheets[sheetIndex];
Cells cells = worksheet.Cells;
Cell cell = null;
//Adding a value to "A1" cell
cell = cells["A1"];
cell.Value = 1;
//Adding a value to "A2" cell
cell = cells["A2"];
cell.Value = 2;
//Adding a value to "A3" cell
cell = cells["A3"];
cell.Value = 3;
//Adding a SUM formula to "A4" cell
cell = cells["A4"];
cell.Formula = "=SUM(A1:A3)";
//Calculating the results of formulas
book.CalculateFormula();
//Saving the Excel file
book.Save("AsposeFormulaEngine.xls");
