Microsoft Excel is bringing the familiar #SPILL! error to PivotTables in Microsoft 365, making it easier for users to identify blocked table areas directly within their worksheets. This update replaces traditional alerts with a dynamic #SPILL indicator whenever a PivotTable can’t expand due to filled cells, helping users troubleshoot layout issues faster without leaving the sheet.
It’s an easier and more direct way to know why a PivotTable doesn’t appear. #SPILL works the same way as it already does for dynamic arrays which don’t have enough empty cells to fill up.
How PivotTable #SPILL works in Excel
Insert, refresh, or otherwise manipulate a PivotTable in Excel 365 (Windows or Mac).
That includes PivotTables made with PivotBy()
If something is blocking the expansion of the PivotTable, the top‑left cell shows a #SPILL! error.

Click on the top-left cell to see the area that the PivotTable wants.
The green alert tag (top-left of the main cell) will show more information about the error e.g. “Spill range isn’t blank”
To un‑#SPILL it:
- Clear the cells that are in the way.
- Move the pivot table to a location with enough free space.
- Use the PivotTable Fields list to reshape your pivot until the error goes away.
- Use slicers and timelines to shrink the PivotTable into the available space
As soon as “the coast is clear”, the PivotTable will appear.

Keep in mind
The PivotTable #SPILL! feature will impact dependent analysis objects (for example, formulas like GETPIVOTDATA, PivotCharts, and macros). But interactive controls like slicers and timelines remain unaffected.
In short: if something downstream is depending on your PivotTable, check it when you see the spill. If something interactive is controlling things, you’re probably safe.
Unnecessary Oversell
As usual, Microsoft can’t help overselling the change. According to Microsoft, Excel currently shows “confusing alerts” that are “breaking your flow”. If a PivotTable is blocked by existing filled cells, this is what you see.

What’s confusing about that? It’s a clear message with a warning about cells that might be erased.
Changing to #SPILL could be thought more confusing because it replaces a clear sentence with an Excel error code.
That said, the change is a good one, as long as the user understands what #SPILL means. Users can stay on the sheet and the PivotTable will appear immediately when the cells are cleared. The area the PivotTable needs is clearly shown.
