Bingo! Downloaded release 208 and the problem is solved!
"Stefan Schukat" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Hello Alistair, which version of pythoncom you are using? In the newer versions there is an support for a "native" safearray (the data type Excel is providing). In older versions the complete array was converted to a tuple which is very time and memory consuming. during this conversion you could run out of memory since you have the Python objects and the COM data in your process. I think in 207 the patch was included.
