XP upgrade options

I'm trying to see about upgrading an old XP desktop so that she can use basic software for video chat, word processing, email, etc. I'm aware that I probably will have to purchase a Windows license. Please help me with the best advice. Thanks.
  • Can XP be upgraded to 7 without loss? Is it worth it?
  • Go directly from XP to Win 10.? A fresh install?
  • Is there test software to see what upgrade it can do?
Thank you for your time and expertise. :)
