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?

您的示例适用于MongoDB 1.6.3和1.7.3。下面的示例是针对1.7.3的。您使用的是旧版本的MongoDB吗?
$ cat > locations.csv
Name,Address,City,State,ZIP
Jane Doe,123 Main St,Whereverville,CA,90210
John Doe,555 Broadway Ave,New York,NY,10010
ctrl-d
$ mongoimport -d mydb -c things --type csv --file locations.csv --headerline
connected to: 127.0.0.1
imported 3 objects
$ mongo
MongoDB shell version: 1.7.3
connecting to: test
> use mydb
switched to db mydb
> db.things.find()
{ "_id" : ObjectId("4d32a36ed63d057130c08fca"), "Name" : "Jane Doe", "Address" : "123 Main St", "City" : "Whereverville", "State" : "CA", "ZIP" : 90210 }
{ "_id" : ObjectId("4d32a36ed63d057130c08fcb"), "Name" : "John Doe", "Address" : "555 Broadway Ave", "City" : "New York", "State" : "NY", "ZIP" : 10010 }

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.
我的需求是导入.csv(没有标题)到远程MongoDB实例。对于mongoimport v3.0.7，以下命令适用于我:
mongoimport -h <host>:<port> -u <db-user> -p <db-password> -d <database-name> -c <collection-name> --file <csv file location> --fields <name of the columns(comma seperated) in csv> --type csv
例如:
mongoimport -h 1234.mlab.com:61486 -u arpitaggarwal -p password -d my-database -c employees --file employees.csv --fields name,email --type csv
下面是导入后的截图:
其中姓名和电子邮件是.csv文件中的列。
C:\wamp\mongodb\bin>mongoexport——db proj_mmm——collection offerings——csv——fieldFile offerings_fields.txt——out offerings_csv
当我试图导入CSV文件时，我得到了一个错误。我所做的。 首先，我用大写字母更改了标题行的列名，并删除了“-”，并在需要时添加了“_”。然后输入下面的命令导入CSV到mongo
$ mongoimport --db=database_name --collection=collection_name --type=csv --file=file_name.csv --headerline
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。
