Create TextBox in which each line has a different Horizontal Alignment with Node.js via C++

You can set the horizontal alignment of your paragraph text using the TextParagraph.getAlignmentType() property.

The following sample code creates three lines and sets the horizontal alignment of each of them.

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

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

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

// Access first worksheet.
const ws = wb.getWorksheets().get(0);

// Add text box inside the sheet.
ws.getShapes().addTextBox(2, 0, 2, 0, 80, 400);

// Access first shape which is a text box and set its text.
const shape = ws.getShapes().get(0);
shape.setText("Sign up for your free phone number.\nCall and text online for free.\nCall your friends and family.");

// Access the first paragraph and set its horizontal alignment to left.
let p = shape.getTextBody().getTextParagraphs().get(0);
p.setAlignmentType(AsposeCells.TextAlignmentType.Left);

// Access the second paragraph and set its horizontal alignment to center.
p = shape.getTextBody().getTextParagraphs().get(1);
p.setAlignmentType(AsposeCells.TextAlignmentType.Center);

// Access the third paragraph and set its horizontal alignment to right.
p = shape.getTextBody().getTextParagraphs().get(2);
p.setAlignmentType(AsposeCells.TextAlignmentType.Right);

// Save the workbook in xlsx format.
wb.save(path.join(dataDir, "output_out.xlsx"), AsposeCells.SaveFormat.Xlsx);
