在Node.js中导出VBA证书到文件或流
请参阅以下示例代码，将VBA证书的原始数据保存到文件中。您可以从提供的链接下载使用此代码的示例excel文件。
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Load your source excel file into workbook object
const workbook = new AsposeCells.Workbook(path.join(dataDir, "sampleVBAProjectSigned.xlsm"));
// Retrieve bytes data of Digital Certificate of VBA Project
const certBytes = workbook.getVbaProject().getCertRawData();
// Save Certificate Data into FileStream
require("fs").writeFileSync(path.join(dataDir, "Cert_out_"), Uint8Array.from(certBytes));
