Hello everyone! I have been using this program in Xplane11 for a long time. The ad says you can export your flight plan in GTN750 format. "Flight plans and flight plan fragments can be loaded, saved and merged all using the common Flight Simulator PLN files as well as X-Plane FMS format version 3 and 11, FSC and FLP files. Flight plans can be exported to the Reality XP GNS 530W / 430W V2, the Reality XP GTN 750/650 Touch and the Flight1 GTN 650/750. More export formats are GPX (GPS Exchange Format, including flown track), PMDG RTE, FLP, X-Plane FMS 3 and 11, Majestic Dash FPR and many more. FS9 PLN and FSC plans can be imported. " I have not found anywhere in the menu or buttons for this particular option. Can someone tell me. Sorry, I am writing through an online translator.

You have to set up the multiexport for this format. See here including a quick start: https://www.littlenavmap.org/manuals/littlenavmap/release/2.6/en/ROUTEEXPORTALL.html
