For a Business application I want to read some XML file every minute.
The idea is that it retains these events for 30 min.
So basically every minute I:
1) read XML (1 to 400 records)
2) process the XML to add some data to it
3) remove events older than 30 min
4) display graphs tables etc based on the leftover records.

As the idea is to run this 24x7 I need to know if someone has experience
with the stability of Excel

thanks in advance
