// Create a new workbook
Workbook wkb = new Workbook();

// Access the first worksheet of the workbook.
Worksheet worksheet = wkb.getWorksheets().get(0);

// Add relevant content in the cell
worksheet.getCells().get("A1").putValue("ColumnA");
worksheet.getCells().get("B1").putValue("ColumnB")
worksheet.getCells().get("A2").putValue("ValueA")
worksheet.getCells().get("B2").putValue("ValueB")

// Save the workbook as XLTX file
wkb.save("Excel.xltx"); 

// To enhance the code for further functionalities here are more functions
// getCells() and setValue for modifying the cell content
// getCharts().add() to add charts
// getPivotTables().add() for creating a Pivot Table
// getCells().get(int cell id).setFormula for adding cell level formula
