Excel files can grow quite large, but performance usually becomes an issue before a crash. The maximum file size is technically limited by available memory and system resources. However, Excel starts to slow down or become unstable with files over 250MB. It's best to keep Excel files below this size for optimal performance and to prevent crashes. Optimizing data, using external data connections, and leveraging Power Pivot can help manage large datasets efficiently.
