Inputting 3 sheets from 1 workbook, edit them, and then outputting all 3 to a new workbook

[ppatane]

I need to input 3 sheets with different schemas from an Excel workbook, do work on each sheet, and then export them all to another workbook with their original tab names.  I keep getting errors when writing the 2nd and 3rd sheets as it says they're in process.  I'd use a Bluck Until Done, but I cannot see how to connect the output to the next container.

We can stick with the Block Until Done while using a Count Record tool to link them together.

You can use @Qiu  solution or use the Parallel Block Until Done. You can use any of these tools to synchronize your WF data output.
