清洗完数据后如何把数据导出的同时导入到mongo里
After processing the data in OpenRefine I would export the data as JSON and then import that JSON data into Mongo. It's been a while since I've used Mongo though so I'm not up-to-date on the best method to bulk insert data. If you're looking for a deeper connection to Mongo (like, say, to export data in their BSON format instead of JSON) you could look into writing an extension, but I'd suggest sticking with simpler tools to get started.
