Thanks for your posting. You can export existing log files to multiple formats in the SmartInspect Console under File | Export Log. You can alternatively look into using the SmartInspect SDK/Resource Kit to read a SmartInspect log file and convert this into the export format of your choice (requires programming experience):
Another alternative would be to generate SmartInspect text log files in addition to or instead of SmartInspect's binary log files, e.g.:
SiAuto.Si.Connections = "text(..)";
I hope this helps and please let me know in case you have any further questions.
