var aspose = aspose || {};
aspose.cells = require("aspose.cells");

var workbook = new aspose.cells.Workbook(aspose.cells.FileFormatType.XLSX);
workbook.getWorksheets().get(0).getCells().get("A1").putValue("testing...");
workbook.save("output.xlsx");

Convert Excel XLSX File to PDF using Node.js

var aspose = aspose || {};
aspose.cells = require("aspose.cells");

var workbook = new aspose.cells.Workbook("example.xlsx");
var saveOptions = aspose.cells.PdfSaveOptions();
saveOptions.setOnePagePerSheet(true);
workbook.save("example.pdf", saveOptions);

Format Excel Cells via Node.js

var aspose = aspose || {};
aspose.cells = require("aspose.cells");

var excel = new aspose.cells.Workbook();
var style = excel.createStyle();
style.getFont().setName("Times New Roman");
style.getFont().setColor(aspose.cells.Color.getBlue());
for (var i = 0; i < 100; i++)
{
    excel.getWorksheets().get(0).getCells().get(0, i).setStyle(style);
}

Add Picture to Excel Worksheet with Node.js

var aspose = aspose || {};
aspose.cells = require("aspose.cells");

var workbook = new aspose.cells.Workbook();
var sheetIndex = workbook.getWorksheets().add();
var worksheet = workbook.getWorksheets().get(sheetIndex);

// adding a picture at "F6" cell
worksheet.getPictures().add(5, 5, "image.gif");
