The LTspice .cir format is a netlist format. It will not open in LTspice as a schematic. If you open your schematic in SIM mode and do File > Export Netlist > LTspice netlist then you can download a netlist which LTspice can open and run. However for this to work your schematic must be a properly constructed simulation schematic using only symbols from the Spice symbol library. If you have used symbols from other libraries then the netlist will be incomplete and will not run in LTspice. This is explained in the Simulation Tutorial. You cannot export an EasyEDA schematic in a format that LTspice can open as a schematic. Why not simply make your project public and post the link to it. Or request assistance - and permission to add - someone who may volunteer to help to add them to your Team? Then you will get eyes on your project for help within EasyEDA.

Make it Public? Ok I'll ask him.It's not my work.
