Read password protected excel file using OLEDB in C#

You need to specify your UserId and Password in your Connection String same as with a SQL connection. Unfortunately, this means that you'll have to get the password.

If you can't get the password, you might be able to open the spreadsheet in Read-Only mode and copy the data from it into a new spreadsheet and read that one...

Assuming you're talking about an Excel file that you're allowed to view but that's locked for editing with a password. I'm fairly certain that OleDB won't support that.

You could probably open the file using Excel Automation and copy the data into your app from there however.
