I am a developer and I have recently developed a tool to manage, save and export GIFT in a fast and simple way. https://www.onlinegiftgenerator.com/
You can try the tool for free for 15 days and then various packages are available.
At the moment for this period up to January 6th there are discounts on packages.
Also for the Moodle community I have generated a coupon valid for 100 packages that gives you an additional 10% discount. "moodle10"
Thank you for your attention and it would be useful to receive feedback from you on how it works. I am open to developing additional features upon request if needed.
Thanks
Giuseppe
