Formula Calculation Engine in Xlsx4j

Aspose.Cells - Formula Calculation Engine

The formula calculation engine is embedded within Aspose.Cells. It can not only recalculate the formulas imported from a designer spreadsheet file, but also supports calculating the results of formulas added at runtime.

Java

 //Instantiating a Workbook object
Workbook book = new Workbook();

//Obtaining the reference of the newly added worksheet
int sheetIndex = book.getWorksheets().add();
Worksheet worksheet = book.getWorksheets().get(sheetIndex);
Cells cells = worksheet.getCells();
Cell cell = null;

//Adding a value to "A1" cell
cell = cells.get("A1");
cell.setValue(1);

//Adding a value to "A2" cell
cell = cells.get("A2");
cell.setValue(2);

//Adding a value to "A3" cell
cell = cells.get("A3");
cell.setValue(3);

//Adding a SUM formula to "A4" cell
cell = cells.get("A4");
cell.setFormula("=SUM(A1:A3)");

//Calculating the results of formulas
book.calculateFormula();

//Saving the Excel file
book.save(dataDir + "AsposeFormulaEngine.xls");
