Excel Limitations -- Excel places limitations on exported reports due to the BIFF's format capabilities. The most significant are the following:
•The maximum number of rows in a worksheet is limited to 65,536. If this is exceeded, the renderer displays an error message.
•The maximum number of columns in a worksheet is limited to 256. If this is exceeded, the renderer displays an error message."
