Hey Toro,
Unfortunately there is no utility that will parse your HTML format files into your DataBase. This is primarily because the report files don't have all the information that is stored in the database. The data stored in the database is quite complex. So you might have to resort to manually inserting the fields, although this process is quite tedious. Also you cannot really convert your HTML files into .csv file, just because once a report is created TestStand doesn't know what data fields of the HTML file is important or not.
I'll place a product suggestion over to R&D to maybe look into creating a utility for our future releases.
