SSIS using source of password-protected Excel Files

    I need to import data from an Excel file into a SQL 2005 DB and thought I would use SSIS since this is a pretty straight forward task for SSIS. However, I just learned that the Excel file is password-protected and I have not found anything online that mentions how to do this since there is no way to distinguish this in the Connection to the Excel file.

    I do know the password to open the file but just don't know how to automate this. Any ideas?

    Important text in the article:

    You cannot connect to a password-protected Excel file.

    Shoot! Anyway to programatically remove the password protection so that it can be used in SSIS?

    Maybe, but unfortunately I don't have any information on that.

    My first thought was that you may be able to use Poweshell. A quick look around and I found this:

    Great, I was able to open the Excel file using Powershell, thanks! Since I'm very new to Powershell, is there a way to save the Excel file without the password now?

    Here's my thoughts. Open the Excel file and save it without the password. Then use SSIS to reference this newly saved file as a source for data flow to get around the limitation of not being able to open it in SSIS with a password.

    Any thouhts?

    Thanks!

    Exactly that. Set password to empty ("") and SaveAs. Then the connection manager shouldn't complain.

    Remove the Password When Opening an Excel Spreadsheet?

    '@

    $xl.Visible = $True

    $xl.DisplayAlerts = $False

    $wb = $xl.Workbooks.Open("C:\Scripts\Test.xls",0,$False,1,"%reTG54w")

    $wb.Password = ""

    $a = $wb.SaveAs( "C:\Scripts\Test.xls")

    $a = Release-Ref($wb)

    $a = Release-Ref($xl)

    I try this and I'm getting the following error on the saveas line:

    Exception calling "SaveAs" with "1" arguments(s): "Cannot access read-only document

    I have "$False" for the readonly parameter on the open method so I don't understand why I'm getting this error.

    Here's the Open statement

    $wb = $xl.Workbooks.Open(<file>,1,$False,5,"abc123","abc123")

    Here's the SaveAs statement

    $a = $wb.SaveAs(<file>)

    Thoughts?

    If you can use third-party solutions, check the commercial CozyRoc Excel components. These are the relevant components:

    * Excel Source component - for reading data from Excel worksheet.

    * Excel Destination component - for writing data in Excel worksheet.

    * Excel Task - for manipulating Excel workbooks.

    * Excel Connection - used by the components above and also for implementing custom scripts based on it.

    The Excel Connection supports opening of password-protected workbooks and doesn't require installation of Office. Cheers!

    i tried the above script but it still prompts me for a password after the type this line

    $wb = $xl.Workbooks.Open("C:\Scripts\Test.xls",0,$False,1,"%reTG54w")

    i have given my password for my excel file for my code.

    im not even able to type the next line unless i enter the password for the excel file. If the close the excel file it throws an error in the powershell!

    Is there any way to solve this issue. The code worked fine two days back!

    thanks in advance

    🙂
