Comment 7 for bug 947100

Sorry for the slow response.

Even the times for a 10x10 table are too slow. Plus, the runtime is superlinear in the size of the input. I suspect a performance problem with the string implementation in Office:mac VBA, but a coarse Google search didn't find anything interesting.

Unfortunately, I still don't have regular access to a Mac. If anyone is willing to investigate this issue I will be more than happy to incorporate working patches.

Perhaps I can at least turn off the interactive preview in the Mac version. Then the dialog remains usable, though the conversion will still take a long time.

Note that the Windows version does not seem to suffer from this performance problem.
