Hello mohammedawni,
I second ManniB's recommendation and would add FRX2ANY. Unfortunately, FRX2ANY is not available on the homepage it used to be offered, I guess it also has no new home.
Just to be clear: These tools run the same old FRX and don't convert it. Just instead of printing the FRX output, they create an HTML file (or other outputs).
There also is such a tool coming with VFP itself: The HTML report listener. I can't tell you if that's already sufficiently working for you, but it's worth trying before using anything else.
If you literally want to convert FRX to something making the FRX obsolete please just note FRX isn't a document format and HTML isn't a report format. But I don't think you really want to convert the FRX, you want HTML as the output format. If not, please clarify your goal.
