This is a (minor) bug caused by the automatic wrapping of datasets as "PyDatasets", which makes them act as sequences and fall down a different code path in functions such as `exportExcel` that accept both single elements and lists. The fix is extremely simple; change: `system.dataset.exportExcel(fName, 1, tablet1)` to: `system.dataset.exportExcel(fName, 1, [tablet1])` To explicitly pass a list of datasets into the function. We're planning to address this and related issues (e.g. with `toExcel`) in an upcoming 8.3 release, but it's not the highest priority since the workaround is so easy. * * * That aside, I'll make an obligatory mention that you should avoid Python/Jython's stdlib `datetime` and prefer to use functions from the `system.date` package, for your sake down the road for maintenance. It's not a big deal for simple string formatting operations as you have here, but for any complicated date math you want to avoid `datetime`. EDIT: There's the original, knew this felt familiar: > [@\[IGN-14447\]system.dataset.toExcel not working after updating to 8.3](https://forum.inductiveautomation.com/t/ign-14447-system-dataset-toexcel-not-working-after-updating-to-8-3/112749/2): > > So, the short version is: Update your script to system.dataset.toExcel(True, [value]) and everything will start working fine. The medium version is that toExcel has always been documented to accept a list of datasets (which will become 'sheets' in the final document, 1:1 with input datasets). That it accepts a single dataset is a convenience feature we're deliberately not documenting because the list form is "more correct". The long version is that this broke with the transition to 8.3 becaus… --- _[View the full topic](https://forum.inductiveautomation.com/t/ign-14447-export-excel-from-power-table/113222)._
