I responded to your email, but I'll also respond here. I don't know much about the .gs2 file format. In order to determine whether any of the data can be extracted from that file to be used in MobileSheetsPro, you (or the developers of Guitar Songbook Pro) would need to provide details on that file format and how the data is packaged. It's definitely not something MobileSheetsPro supports currently though. I'm not sure about your background so I'll try not to get too technical, but if you examine the file in something like NotePad++, does the data look garbled or is it human-readable?

You can't do anything through a browser, but MobileSheets is available for Windows 10 devices through the Microsoft Store, while MobileSheetsPro is available for Android devices through the Google Play store. The two are functionally equivalent.
