Output tool error - file locked because it is in use by another process

[KateC]

I have a workflow that writes to one Excel worksheet in three different sections (using a template). I have Block Until Done tools in place and it has worked for the past 5 months. Suddenly, I can't do this and nothing has changed in the workflow. It's like the Block tools aren't working. How to troubleshoot?

Is it possible that someone else has the file open or is locked?  Are you able to open the file itself in Excel?

[KateC]

I can open the file and nobody else has it open. I noticed yesterday in another workflow that worksheets were written in the wrong order in an Excel file despite having Block Until Done tools in place. I think it's an issue with the tool itself. Is that possible?

 did you update the workflow to amp?

Problem solved. I added a container to isolate one leg of the workflow and minimized it. The workflow still threw and error but it was more accurate. There was a formula in one cell of my template and Alteryx couldn't overwrite that cell.
