Hi @giffinromeo , I presume that in the above screenshot, the Write to Excel Template node is being used totally independently of the Excel Writer and XLSFormatter (plus the other components)?
Take a look at this thread which I think discussed a similar use case re writing multiple sheets.
If that doesn’t give any ideas, then please can you put together a small minimal workflow that demonstrates what you are trying to do (and without any nodes which aren’t part of the problem), as it’s really difficult offering advice based simply on a screenshot.
