Specify the Language of the Excel File using BuiltIn Document Properties with Node.js via C++

Possible Usage Scenarios

You can change the language of an Excel file by right‑clicking the file, selecting Properties > Details, and editing the Language field. Please use BuiltInDocumentPropertyCollection.getLanguage() to change it programmatically using Aspose.Cells for Node.js via C++ APIs.

Specify the Language of the Excel File using BuiltIn Document Properties

The following sample code creates a workbook and changes its built‑in document property named Language. Please see the output Excel file generated by the code and the screenshot that shows the modified Language field using the BuiltInDocumentPropertyCollection.getLanguage() property.

Sample Code

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

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

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

// Access built‑in document property collection.
const bdpc = wb.getBuiltInDocumentProperties();

// Set the language of the Excel file.
bdpc.setLanguage("German, French");

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