Is there any way to generate password protected XLSX in NodeJS?

问题

I am looking for an npm package or any other workaround to be able to generate xlsx file with password. I do not want to protect the sheet(s) or cell(s)... I want the whole file password protected. I found few quite good packages (excel4node, exceljs..) but none of them able to do what I need.

Any suggestion appreciated

回答1:

You can use the xlsx-populate module to do this, for example:

const XlsxPopulate = require('xlsx-populate');

XlsxPopulate.fromBlankAsync().then(workbook => {
    workbook.sheet("Sheet1").cell("A1").value("Some sample text");
    return workbook.toFileAsync("./test.xlsx", { password: "$secret_password" });
});

The resulting workbook will require the user to enter the correct password if they wish to access it.

you can use exceljs package, it provides a way to create write protected excel, but does not provide password protected excel sheet.

await worksheet.protect('the-password', options);

But if you want to create a password protected excel sheet then you can use xlsx-populate package.

XLSX Agile encryption and decryption are supported so you can read and write password-protected workbooks. To read a protected workbook, pass the password in as an option:

XlsxPopulate.fromFileAsync("./Book1.xlsx", { password: "S3cret!" })
.then(workbook => {
    // ...
});

Similarly, to write a password encrypted workbook:

workbook.toFileAsync("./out.xlsx", { password: "S3cret!" });
