My objective is to convert TXT file into EXCEL file using Script Task in SSIS Package.
My customer has received the TXT file from External vendor and has requested my department to automatically converted this TXT file to EXCEL file for them.
My approach is to use script task in SSIS package to convert this TXT file into EXCEL file.
I have created the following variable names:
-
DestinationFolderPath =
\Fileserv02\Shared Folders\Loan Sales & Servicing\BI Reports - Weekly & Monthly\LSS DestinationFolder -
FileDelimiter
, -
FileExtension
.TXT -
SourceFolderPath
\Fileserv02\Shared Folders\Loan Sales & Servicing\BI Reports - Weekly & Monthly\LSS SourceFolder\
I would like to share my script task code below:

#region Help: Using Integration Services variables and parameters in a script
/* To use a variable in this script, first ensure that the variable has been added to
* either the list contained in the ReadOnlyVariables property or the list contained in

* code needs to write to the variable. To add the variable, save this script, close this instance of

* ReadWriteVariables properties in the Script Transformation Editor window.
* To use a parameter in this script, follow the same steps. Parameters are always read-only.
*
* Example of reading from a variable:
* DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
*
* Example of writing to a variable:
* Dts.Variables["User::myStringVariable"].Value = "new value";

* Example of reading from a package parameter:

I am getting an error message "Not a valid file name" and I am not sure why.
Any advice and/or help will certainly be appreciated.
Thank you,
