We recommend the easyeda2kicad python package instead.
Convert EasyEDA PCBs to KiCad format
The easiest way to convert EasyEDA boards to KiCad format is to use the online convertor:
https://wokwi.com/easyeda2kicad
npm install -g easyeda2kicad
easyeda2kicad <input.json> [output.kicad_pcb]
Copper zones are converted but not filled. When you load the converted PCB in KiCad press "b" (or "Edit" → "Fill All Zones") to recalculate the zones.
