How to read multiple Excel files in SSIS


Reading multiple Excel files in SSIS can be a common requirement in many data integration scenarios. SSIS (SQL Server Integration Services) offers a robust framework for extracting, transforming, and loading data, but handling Excel files efficiently can be a challenge. However, with the ZappySys SSIS PowerPack, this task becomes streamlined and straightforward.


Ensure you have the following installed:

  1. SQL Server Data Tools (SSDT): Install SQL Server Data Tools, the development tool for SSIS.
  2. ZappySys SSIS PowerPack: Download and install the ZappySys SSIS PowerPack.

You can use SSIS Excel Source Component to read multiple Excel files in SSIS, you can find the documentation of the component here.
SSIS Excel File Source Connector (Advanced Excel Source) can be used to read the Excel file without installing any Microsoft Office Driver. You can extract using Table mode or query mode (SQL Command). Support for flexible metadata detection mode so you can get accurate data types.

Note: If you want to operate with multiple files then use the wildcard pattern as below (when you use the wildcard pattern in the source path then the system will treat the source path as a folder regardless you end with a slash).
c:\SSIS\Excel\file123.xlsx (single file).
c:\SSIS\Excel\file*.xlsx (all files starting with name file).
c:\SSIS\Excel\subfolder\*.xlsx (all files with .xlsx Extension and located under folder subfolder).
