Large datasets and complex formulas are the primary culprits in slowing down Excel. Excessive use of volatile functions, such as INDIRECT and OFFSET, can also significantly reduce performance. Conditional formatting, links to external files, and animated objects further contribute to sluggishness. To optimize speed, consider simplifying formulas, limiting volatile functions, and breaking down large datasets into smaller, manageable chunks.
