Loading and managing Excel, OpenOffice, Json, Csv and Html files

Creating a New Workbook

The following example creates a new workbook from scratch.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const licensePath = path.join(dataDir, "Aspose.Cells.lic");

try {
// Create a License object
const license = new AsposeCells.License();

// Set the license of Aspose.Cells to avoid the evaluation limitations
license.setLicense(licensePath);
} catch (ex) {
console.log(ex.message);
}

// Instantiate a Workbook object that represents Excel file.
const wb = new AsposeCells.Workbook();

// When you create a new workbook, a default "Sheet1" is added to the workbook.
const sheet = wb.getWorksheets().get(0);

// Access the "A1" cell in the sheet.
const cell = sheet.getCells().get("A1");

// Input the "Hello World!" text into the "A1" cell
cell.putValue("Hello World!");

// Save the Excel file.
wb.save(path.join(dataDir, "MyBook_out.xlsx"));

Opening and saving a File

With Aspose.Cells, it is simple to open, save and manage Excel files.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Opening through Path
// Creating a Workbook object and opening an Excel file using its file path
const workbook1 = new AsposeCells.Workbook(path.join(dataDir, "Book1.xlsx"));
// Adding new sheet
const sheet = workbook1.getWorksheets().add("MySheet");
// Setting active sheet
workbook1.getWorksheets().setActiveSheetIndex(1);
// Setting values.
const cells = sheet.getCells();
// Setting text
cells.get("A1").putValue("Hello!");
// Setting number
cells.get("A2").putValue(1000);
// Setting Date Time
const cell = cells.get("A3");
cell.putValue(new Date());
const style = cell.getStyle();
style.setNumber(14);
cell.setStyle(style);
// Setting formula
cells.get("A4").setFormula("=SUM(A1:A3)");
// Saving the workbook to disk.
workbook1.save(path.join(dataDir, "dest.xlsx"));
