Structured formula builder
Task, table context, target range, and function hint keep the request specific.
Excel #SPILL! error fixer
#SPILL! means your formula tried to return more than one cell of results and Excel could not place those results in the grid. Paste the formula, describe the spill range, and get a revised formula path with the checks to make before you use it.

Use case
Help Excel users repair one formula that wants to spill multiple results but is blocked by occupied cells, merged cells, table behavior, worksheet edges, volatile array size, or an oversized reference.
Use this page when Excel returns #SPILL! because a dynamic array formula wants to return multiple cells but cannot place them in the grid. It is strongest when you can paste the formula, name the formula cell, and describe the intended spill range.
Do not treat #SPILL! as only a syntax error. The formula may be valid, but the surrounding cells, table layout, merged cells, or reference size may prevent Excel from placing the result.
A FILTER formula can return #SPILL! when it should return open rows, but another value is already sitting where the filtered results need to appear.
=FILTER(A2:C500,B2:B500="Open","No open rows")
The formula filters rows where Status equals Open and includes a no-match fallback. Before replacing the formula, clear the intended spill range and confirm the result starts outside an Excel table.
