Hello,
I need to be able to protect Excel files with password as seen here: https://support.microsoft.com/en-us/office/protect-an-excel-file-7359d4ae-7213-4ac2-b058-f75e9311b59...
But, I need to do it programmatically.
I have a PHP app that creates Excel files, then saves them, then allows users to download them.
I want to be able to add password to them via the PHP code.
I know I can't do it directly via PHP, but, is there any other language I can write a password protecting script, then run the script via the PHP code? For example writing some bash script, and using PHP's `exec` to run it. Or any other language. (Even if it would be some other file type, just that I can run it from the PHP side)

You can achieve programmatically protecting Excel files with a password by using a scripting language that can interact with the Excel application. One such scripting language is Visual Basic for Applications (VBA), which is built into Excel.
Here's an example of how you can create a VBA script to password protect an Excel file, and then execute it from PHP using the exec function:
vbacode
Sub ProtectExcelFile()
Dim filePath As String
Dim password As String
' Set the file path of the Excel file to be protected
filePath = "C:\path\to\your\excel_file.xlsx"
' Set the desired password for protection
password = "your_password"
' Open the workbook with the provided file path and password protect it
Workbooks.Open filePath
ActiveWorkbook.Password = password
ActiveWorkbook.Save
ActiveWorkbook.Close
' Close the Excel application
Application.Quit
End Sub
php code
<?php
$excelFilePath = "C:\path\to\your\excel_file.xlsx";
$vbaScriptPath = "C:\path\to\your\vba_script.xlsm";
// Copy the Excel file to a new file with the .xlsm extension to enable macros
$macroEnabledFilePath = $excelFilePath . "m";
copy($excelFilePath, $macroEnabledFilePath);
// Create a separate workbook to hold the VBA script
copy($vbaScriptPath, "vba_script.xlsm");
// Execute the VBA script using the Excel application
exec("excel.exe vba_script.xlsm");
// Delete the temporary workbook and VBA script file
unlink($macroEnabledFilePath);
unlink("vba_script.xlsm");
?>
This approach allows you to execute the VBA script from PHP by using the exec function and interacting with the Excel application. The text, steps and code/functions were created with the help of AI. My answers are voluntary and without guarantee!
