Unprotect a Worksheet with Node.js via C++

If a developer needs to remove protection from a protected worksheet at runtime so that some changes can be made to the file? This can easily be done with Aspose.Cells.

Unprotect a Worksheet

Using Microsoft Excel

To remove protection from a worksheet:

From the Tools menu, select Protection followed by Unprotect Sheet. Protection will be removed unless the worksheet is password protected. In this case, a dialog prompts for the password. Enter the password and the worksheet will be unprotected then.

Unprotecting a Simply Protected Worksheet Using Aspose.Cells

A worksheet can be unprotected by calling the Worksheet class' unprotect() method. A simply protected worksheet is one which is not protected with a password. Such worksheets can be unprotected by calling the unprotect() method without passing a parameter.

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

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook(filePath);

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Unprotecting the worksheet without a password
worksheet.unprotect();

// Saving the Workbook
workbook.save(path.join(dataDir, "output.xls"), AsposeCells.SaveFormat.Excel97To2003);

Unprotecting a Password Protected Worksheet Using Aspose.Cells

A password protected worksheet is one that is protected with a password. Such worksheets can be unprotected by calling an overloaded version of the unprotect() method that takes the password as a parameter.

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

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook(filePath);

// Accessing the first worksheet in the Excel file
const worksheet = workbook.getWorksheets().get(0);

// Unprotecting the worksheet with a password
worksheet.unprotect("");

// Save Workbook
workbook.save(path.join(dataDir, "output.out.xls"));
