    Hi Rajesh,

    This error message seems to inficate that an eumerated collection was modified during while the colletion was being enumerated. If that's occurring inside the BIFF8Writer, then it's either a threading issue or a bug.

    Is your application using multiple threads?

    Are you able to duplicate this exception in a small sample project?
