How to Create Signature Line for Excel

Aspose.Cells for Node.js via C++ also provides this feature and has exposed the Picture.getSignatureLine() property for this purpose. This article will explain how to use this property to add a Signature Line using Aspose.Cells.

The following sample code adds a Signature Line using Picture.getSignatureLine() property and saves the workbook.

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

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

// Create workbook object
const workbook = new AsposeCells.Workbook();

// Create signature line object
const signatureLine = new AsposeCells.SignatureLine();
signatureLine.setSigner("John Doe");
signatureLine.setTitle("Development Lead");
signatureLine.setEmail("[e-mail]");

// Adds a Signature Line to the worksheet.
workbook.getWorksheets().get(0).getShapes().addSignatureLine(1, 1, signatureLine);

// Save the workbook
workbook.save(path.join(dataDir, "output_out.xlsx"));
