包含联系方式的CSV文件:
Name,Address,City,State,ZIP
Jane Doe,123 Main St,Whereverville,CA,90210
John Doe,555 Broadway Ave,New York,NY,10010
运行这个不会向数据库添加文档:
$ mongoimport -d mydb -c things --type csv --file locations.csv --headerline
Trace说导入了1个对象，但是在MongoDB shell中运行db.things.find()不会显示任何新文档。
我错过了什么?

分享给未来的读者:
在本例中，我们需要添加host参数以使其工作
mongoimport -h mongodb://someMongoDBhostUrl:somePORTrunningMongoDB/someDB -d someDB -c someCollection -u someUserName -p somePassword --file someCSVFile.csv --type csv --headerline --host=127.0.0.1

I was perplexed with a similar problem where mongoimport did not give me an error but would report importing 0 records. I had saved my file that didn't work using the OSX Excel for Mac 2011 version using the default "Save as.." "xls as csv" without specifying "Windows Comma Separated(.csv)" format specifically. After researching this site and trying the "Save As again using "Windows Comma Separated (.csv)" format, mongoimport worked fine. I think mongoimport expects a newline character on each line and the default Mac Excel 2011 csv export didn't provide that character at the end of each line.
检查文件末尾是否有空行，否则在某些版本的mongoimport上最后一行将被忽略
使用:
mongoimport -d 'database_name' -c 'collection_name' --type csv --headerline --file filepath/file_name.csv
以上这些答案都很棒。这也是开发一个功能齐全的应用程序的方法。
但是如果你想要快速创建原型，想要在集合不断变化时保持灵活性，以及最小化你早期的代码库，有一种更简单的方法，但很少讨论。
你现在基本上可以放弃蒙古进口了。如果在这里提到这个问题，我可以节省3个小时。让我分享给大家:
Mongodb有一个名为Mongo Compass的GUI，它有csv和json导入功能，只需点击即可开箱即用。它是Mongo生态系统的正式组成部分。在撰写本文时，它是免费的，并且非常适合我的用例。 https://www.mongodb.com/products/compass
You simply get MongoDB compass running on your machine by following the simple installation. A couple of fields for DB connection and authentication directly in the GUI. Import the csv/json file. It took less than a second on a 30KB file to be parsed before user (me) validates. Validate the "type" of each property. Great feature, I could directly mention the property types such as booleans, integers, etc. In my experience, they seem all default to string. You can update before importing. Dates were more finicky and needed special attention on the coding side. One click further the csv is a collection in your mongo db local or on the cloud. Voila!
mongoimport -d test -c test——type csv——file SampleCSVFile_119kb.csv——headerline .csv
检查采集数据:—
var collections = db.getCollectionNames(); For (var I = 0;我< collections.length;我+ +) ｛ print('Collection: ' + collections[i]); //打印每个集合的名称 db.getCollection(集合[我]);().forEach (printjson); //然后打印每个元素的json ｝
