I have Amazing designs apps and also an old version of Letter it. Both are good and I can save in whatever format I want.

There is a free software called Embrilliance Express that makes lettering & monogramming so easy. (I bought the Alpha Tricks program from Embrilliance & would be lost without it.) Many of the embroidery sites that have embroidery fonts & alphabets have them available in the .BX format which is proprietary to Embrilliance. Here are some links to help you see what this program will do.

Embrilliance works with both Windows & Mac & all updates are free.
There are also Facebook groups & a forum for additional help.

I am a Bernina girl. Most softwares should do lettering for you. Do you have a dealer? Check with them to see what they offer lessons with their software. Kay
