SSIS Excel Connection Manager failed to Connect to the Source
The workaround is, I save the excel file as excel 97-2003 then it works fine
I also ran into this problem today, but found a different solution from using Excel 97-2003. According to Maderia, the problem is SSDT (SQL Server Data Tools) is a 32bit application and can only use 32bit providers; but you likely have the 64bit ACE OLE DB provider installed. You could play around with trying to install the 32bit provider, but you can't have both the 64 & 32 version installed at the same time. The solution Maderia suggested (and I found worked for me) was to set the DelayValidation = TRUE on the tasks where I'm importing/exporting the Excel 2007 file.
It seems like the 32-bit version of Excel was not installed. Remember that SSDT is a 32-bit IDE. Therefore, when data is access from SSDT the 32-bit data providers are used. When running the package outside of SSDT it runs in 64-bit mode (not always, but mostly) and uses the 64-bit data providers.
Always keep in mind that if you want to run your package in 64-bit (which you should aim for) you will need both the 32-bit data providers (for development in SSDT) as well as the 64-bit data providers (for executing the package in production).
I downloaded the 32-bit access drivers from:
- Microsoft Access Database Engine 2010 Redistributable.
After installation, I could see the worksheets
