This is not a common error to receive, but it can happen:
This is an Excel-specific issue that is related to memory allocation for the Excel sheet you are trying to create.
As this is an Excel problem, it is not something we are able to correct.
Most of the time, the error simply goes away on its own if you attempt the conversion again but, on occasion, it may be necessary to reinstall your Excel application or try converting to a different format.
We regret that we are not able to help you solve this problem, but we do not support Excel.
