From my understanding, XLS files are currently the only straight forward way to add your own data from files. I have played around with OddsMiner but it doesn't have all the data I need. Also, I don't know the layout of the league files (.lea) or the soccerway html files so I can't create those. It would be fantastic if OddsWizard could be updated to allow import from csv files since it would be extremely easy to have the first row in the csv file match the headers in OW. I prefer csv over xls files since I can create csv files automatically using my own code but creating xls files is not very straightforward outside of the Excel application.
If I am missing something when it comes to adding your own data to OW, please let me know since as long as I have a format in some plain text layout that I can import into OW, I can always re-write my code to create those formats, but csv files would be by far the easiest.
