Multiple process running same time but outputting to the same spreadsheet

[Taki]

Hi:

I am trying to run multiple process at the same time but want to output to the same excel spreadsheet with different tabs. I am getting an error when writing that the spreadsheet is being used by another process. Appreciate anyone who can show me how to do this.  Thanks,

Thanks for sharing the "Parallel Block Until Done" Macro. It really helped!
