Insert json file into mongodb

问题:

I am new in mongodb. After installing mongodb in windows I am trying to insert a simple json file using the following command:

C:\>mongodb\bin\mongoimport --db test --collection docs < example2.json

I am getting the following error:

example2.file

{"FirstName": "Bruce", "LastName": "Wayne", 
"Email": "[e-mail]"}
{"FirstName": "Lucius", "LastName": "Fox", 
"Email": "[e-mail]"}
{"FirstName": "Dick", "LastName": "Grayson", 
"Email": "[e-mail]"}

What do I need to do to import new json file into mongodb?

回答1:

Use

mongoimport --jsonArray --db test --collection docs --file example2.json

Its probably messing up because of the newline characters.

回答2:

Below command worked for me

mongoimport --db test --collection docs --file example2.json

when i removed the extra newline character before Email attribute in each of the documents.

example2.json

{"FirstName": "Bruce", "LastName": "Wayne", "Email": "[e-mail]"}
{"FirstName": "Lucius", "LastName": "Fox", "Email": "[e-mail]"}
{"FirstName": "Dick", "LastName": "Grayson", "Email": "[e-mail]"}

回答3:

This worked for me - ( from mongo shell )

var file = cat('./new.json');     # file name
use testdb                        # db name
var o = JSON.parse(file);         # convert string to JSON
db.forms.insert(o)                # collection name

回答4:

Use below command while importing JSON file

C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs --file example2.json

回答5:

mongoimport --jsonArray  -d DatabaseN -c collectionName /filePath/filename.json

回答6:

In MS Windows, the mongoimport command has to be run in a normal Windows command prompt, not from the mongodb command prompt.

回答7:

It happened to me couple of weeks back. The version of mongoimport was too old. Once i Updated to latest version it ran successfully and imported all documents.

回答8:

the following two ways work well:

C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs --file example2.json
C:\>mongodb\bin\mongoimport --jsonArray -d test -c docs < example2.json

if the collections are under a specific user, you can use -u -p --authenticationDatabase
