Hi,
Apologies in advance if this is in the wrong section. I am currently using Calibre to convert MOBI books to EPUB, then using Sigil to correct typos and small errors. Unfortunately the conversion process seems to create more problems than it allows me to solve. I believe this is partially because the Sigil software is a little over my head, as I can't read or write the html-like code. So I am wondering if there a simpler way to correct the MOBI files? Or is this simply a case of it being more trouble than it's worth for a layman?
Any advice is appreciated

Thanks.
