将 json 文件插入到 mongodb 中

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": "bwayne@Wayneenterprises.com"}
{"FirstName": "Lucius", "LastName": "Fox", "Email": "lfox@Wayneenterprises.com"}
{"FirstName": "Dick", "LastName": "Grayson", "Email": "dgrayson@Wayneenterprises.com"}

Use

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

Its probably messing up because of the newline characters.

Use below command while importing JSON file

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

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

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.

Reference: http://docs.mongodb.org/master/tutorial/install-mongodb-on-ubuntu/?_ga=1.11365492.1588529687.1434379875

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

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

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

This solution is applicable for Windows machine.

1. MongoDB needs data directory to store data in. Default path is C:\data\db. In case you don't have the data directory, create one in your C: drive, unless different VolumeName is used e.g. H: (or any other relevant VolumeName) which is the root of your machine;

2. Place the .json file you want to import within: C:\data\db\ .

3. Before running the command copy-paste mongoimport.exe from C:\Program Files\MongoDB\Tools\100\bin (default path for mongoimport.exe) to the directory of the C:\Program Files\MongoDB\Server\[your_server_version]\bin

4. Open the command prompt from within C:\data\db\ and type the following command by supporting the specific databasName, collectionName and fileName.json you wish to import :

mongoimport --db databaseName --collection collectionName --file fileName.json --type json --batchSize 1

Hereby,

• batchSize can be any integer as per your wish

In MongoDB To insert Json array data from file(from particular location from a system / pc) using mongo shell command. While executing below command, command should be in single line.

var file = cat('I:/data/db/card_type_authorization.json'); var o = JSON.parse(file); db.CARD_TYPE_AUTHORIZATION.insert(o);

JSON File: card_type_authorization.json

[{
"code": "visa",
"position": 1,
"description": "Visa",
"isVertualCard": false,
"comments": ""
},{
"code": "mastercard",
"position": 2,
"description": "Mastercard",
"isVertualCard": false,
"comments": ""
}]

Open command prompt separately and check:

C:\mongodb\bin\mongoimport --db db_name --collection collection_name< filename.json

It works with JS and Node

Preconditions:

• Node
• Mongo - either local installed or via Atlas

server.js:

var MongoClient = require('mongodb').MongoClient;
var fs = require('fs')


export function insert(coll) {
MongoClient.connect('uri', (err, db) => {
var myobj = fs.readFileSync("shop.json").toString()
myobj = JSON.parse(myobj)


db.db(dbWeb).collection(coll).insertMany(myobj, (err, res) => {
db.close();
});
});
}

shop.json:

[
{
"doc": "jacke_bb",
"link": "http://ebay.us/NDMJn9?cmpnId=5338273189",
},
{
"doc": "schals",
"link": "https://www.ebay-kleinanzeigen.de/s-anzeige/4-leichte-schals-fuer-den-sommer/2082511689-156-7597",
}

]

As one see, the json starts with [ and ends with ] and the insertMany is used. This leads to a correct nested insertion of the array into the collection.
