Hello Nitin
If you mouse hover “Execution Time” tab (http://www.sqltest.org/Help/ExecutionTime) numbers, you will see Minimum, Average and Maximum time.
There is a copy button (http://www.sqltest.org/Help/Copy) on the top left of the “Execution Time” tab which will copy Average numbers to clipboard, which you can later paste it to Excel.
The report with Detailed statistics (http://www.sqltest.org/Help/GeneralSettings/InReportIncludeDetailedStatistics) also provides Minimum, Average and Maximum time. This is in XML, you need to convert this into row sets.
There is no automatic way to save to Excel. Currently there is no automated way to convert Report XML into tables, I will work on it and update here when it is done.
Best Regards
