В любом случае, похоже, что ваша проекция / система координат не WGS84:
Я имею в виду, ваш гео json теперь действителен, но большинство конечно не то, что вы на самом деле нарисовали. Поэтому перед экспортом из QGIS убедитесь, что вы выбрали правильную систему координат. 5se c googling: https://gis.stackexchange.com/a/35595 или http://jonathansoma.com/tutorials/mapping/change-crs-with-qgis/
