Create Xlsx Files With Worksheet Security Settings

Aside from the Document Security Settings, there is another similar security option the can be applied on a worksheet level. This can provide the option to allow sorting, inserting rows, and formatting cells, to name a few.

One major difference between the Document Security Settings and this Worksheet Security Settings is, the option to add a ‘New sheet’ is available on the Worksheet Security Settings.

Note:

This will NOT prevent the document from opening, it will only hold back the data from being updated.

// Create a new Spreadsheet object
$spreadsheet = new Spreadsheet();

// Retrieve the current active worksheet
$sheet = $spreadsheet->getActiveSheet();

// Set cell A1 with the "Hello World !" string value
$sheet->setCellValue('A1', 'Hello World !');

/**
 * Set the worksheet protection to 'true',
 * this is a requirement to enable it.
 */
$sheet->getProtection()->setSheet(true);

/**
 * Protect worksheet and
 * contents of locked cells.
 */
$protection = $sheet->getProtection();
$protection->setPassword('HelloWorld!');
$protection->setSort(true); // allow sorting

// Write a new .xlsx file
$writer = new Xlsx($spreadsheet);

// Save the new .xlsx file
$writer->save('create-xlsx-files-with-worksheet-security-settings.xlsx');

create-xlsx-files-with-worksheet-security-settings.php

Test.

Run the following codes.

$ php create-xlsx-files-with-worksheet-security-settings.php

command line

Open the generated file create-xlsx-files-with-worksheet-security-settings.xlsx.

/**
 * Set the worksheet protection to 'true',
