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?

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.

1]We can save xsl as .csv file
2] Got to MongoDB bin pathon cmd - > cd D:\Arkay\soft\MongoDB\bin
3] Run below command
> mongoimport.exe -d dbname -c collectionname --type csv --file "D:\Arkay\test.csv" --headerline
4] Verify on Mongo side using below coomand.
>db.collectioname.find().pretty().limit(1)
如果您在生产环境中工作，则很可能需要进行身份验证。您可以使用类似的方法对具有适当凭证的正确数据库进行身份验证。
mongoimport -d db_name -c collection_name --type csv --file filename.csv --headerline --host hostname:portnumber --authenticationDatabase admin --username 'iamauser' --password 'pwd123'
给定.csv文件，我只有一个列，没有标题，下面的命令对我有用:
mongoimport -h <mongodb-host>:<mongodb-port> -u <username> -p <password> -d <mongodb-database-name> -c <collection-name> --file file.csv --fields <field-name> --type csv
其中field-name指的是.csv文件中列的Header名称。
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
只需在执行mongoimport后使用它
它将返回导入对象的数量
use db
db.collectionname.find().count()
将返回对象的数目。
