Mongoimport of JSON file
JsonMongodbImportMongoimportJson Problem Overview
I have a JSON file consisting of about 2000 records. Each record which will correspond to a document in the mongo database is formatted as follows:
{jobID:"2597401",
account:"XXXXX",
user:"YYYYY",
pkgT:{"pgi/7.2-5":{libA:["libpgc.so"],flavor:["default"]}},
startEpoch:"1338497979",
runTime:"1022",
execType:"user:binary",
exec:"/share/home/01482/XXXXX/appker/ranger/NPB3.3.1/NPB3.3-MPI/bin/ft.D.64",
numNodes:"4",
sha1:"5a79879235aa31b6a46e73b43879428e2a175db5",
execEpoch:1336766742,
execModify: new Date("Fri May 11 15:05:42 2012"),
startTime: new Date("Thu May 31 15:59:39 2012"),
numCores:"64",
sizeT:{bss:"1881400168",text:"239574",data:"22504"}},
Each record is on a single line in the JSON file, and the only line breaks are at the end of every record. Therefore, each line in the document starts with "{jobID:"... I am trying to import these into a mongo database using the following command:
mongoimport --db dbName --collection collectionName --file fileName.json
However, I get the following error:

Solution 1 - Json
I was able to fix the error using the following query:
mongoimport --db dbName --collection collectionName --file fileName.json --jsonArray
Hopefully this is helpful to someone.
Solution 2 - Json
try this,
mongoimport --db dbName --collection collectionName <fileName.json
Example,
mongoimport --db foo --collection myCollections < /Users/file.json
connected to: *.*.*.*

Issue is because of you date format.
I used same JSON with modified date as below and it worked
{jobID:"2597401",
account:"XXXXX",
user:"YYYYY",
pkgT:{"pgi/7.2-5":{libA:["libpgc.so"],flavor:["default"]}},
startEpoch:"1338497979",
runTime:"1022",
execType:"user:binary",
exec:"/share/home/01482/XXXXX/appker/ranger/NPB3.3.1/NPB3.3-MPI/bin/ft.D.64",
numNodes:"4",

hope this helps

Using mongoimport you can able to achieve the same
mongoimport --db test --collection user --drop --file ~/downloads/user.json
where,
test - Database name
user - collection name
user.json - dataset file
--drop
is drop the collection if already exist.
Solution 4 - Json
console:
mongoimport -d dbName -c collectionName dataFile.js
Solution 5 - Json
Your syntax appears completely correct in:
mongoimport --db dbName --collection collectionName --file fileName.json
Make sure you are in the correct folder or provide the full path.
Solution 6 - Json
I have used below command for export DB
mongodump --db database_name --collection collection_name
and below command worked for me to import DB
mongorestore --db database_name path_to_bson_file

Import JSON/CSV file in MongoDB
- wait wait
- first check mongoimport.exe file in your bin folder(C:\Program Files\MongoDB\Server\4.4\bin) if it is not then download mongodb database tools(https://www.mongodb.com/try/download/database-tools)
- copy extracted(unzip) files(inside unzipped bin) to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
- copy your json file to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
- Now open your commond prompt change its directory to bin
cd "C:\Program Files\MongoDB\Server\4.4\bin"
- Now copy this on your commnad prompt
mongoimport -d tymongo -c test --type json --file restaurants.json
- where d- database(tymongo-database name), c-collection(test-collection name)
FOR CSV FILE
mongoimport -d tymongo -c test --type csv --file database2.csv --headerline
Solution 8 - Json
Run the import command in another terminal. (not inside mongo shell.)
mongoimport --db test --collection user --drop --file ~/downloads/user.json
Solution 9 - Json
In windows you can use your Command Prompcmd cmd
, in Ubuntu you can use your terminal
by typing the following command:
mongoimport -d your_database_name -c your_collection_name /path_to_json_file/json_file_name.json
then when you open your mongo shell, you will find to check your database_name when running this command:
show databases
Solution 10 - Json
This command works where no collection is specified .
mongoimport --db zips "\MongoDB 2.6 Standard\mongodb\zips.json"
Mongo shell after executing the command
connected to: 127.0.0.1
no collection specified!
using filename 'zips' as collection.

Solution 12 - Json
I tried something like this and it actually works:
mongoimport --db dbName --file D:\KKK\NNN\100YWeatherSmall.data.json
Solution 13 - Json
This works with me when db with usrname and password
mongoimport --db YOUR_DB --collection MyCollection --file /your_path/my_json_file.json -u my_user -p my_pass
db without username password please remove -u my_user -p my_pass
My sample json
{
"_id" : ObjectId("5d11c815eb946a412ecd677d"),
"empid" : NumberInt(1),
"name" : "Rahul"
}
{
"_id" : ObjectId("5d11c815eb946a412ecd677e"),
"empid" : NumberInt(2),
"name" : "Rahul"
}
Solution 14 - Json
- Just copy path of json file like example "C:\persons.json"
- go to C:\Program Files\MongoDB\Server\4.2\bin
- open cmd on that mongodb bin folder and run this command
mongoimport --jsonArray --db dbname--collection collectionName--file FilePath
example mongoimport --jsonArray --db learnmongo --collection persons --file C:\persons.json

Number of answer have been given even though I would like to give mine command . I used to frequently. It may help to someone.
mongoimport original.json -d databaseName -c yourcollectionName --jsonArray --drop
Solution 16 - Json
> mongoimport -d <dbname> -c <collectio_name> --file <c:\users\test.json> --jsonArray
Solution 17 - Json
If you try to export this test collection:
> db.test.find()
{ "_id" : ObjectId("5131c2bbfcb94ddb2549d501"), "field" : "Sat Mar 02 2013 13:13:31 GMT+0400"}
{"_id" : ObjectId("5131c2d8fcb94ddb2549d502"), "field" : ISODate("2012-05-31T11:59:39Z")}
with mongoexport (the first date created with Date(...)
and the second one created with new Date(...)
(if use ISODate(...)
will be the same as in the second line)) so mongoexport output will be looks like this:
{ "_id" : { "$oid" : "5131c2bbfcb94ddb2549d501" }, "field" : "Sat Mar 02 2013 13:13:31 GMT+0400" }
{ "_id" : { "$oid" : "5131c2d8fcb94ddb2549d502" }, "field" : { "$date" : 1338465579000 } }
So you should use the same notation, because strict JSON doesn't have type Date( <date> )
.
Also your JSON is not valid: all fields name must be enclosed in double quotes, but mongoimport works fine without them.
You can find additional information in mongodb documentation and here.

A bit late for probable answer, might help new people. In case you have multiple instances of database:
mongoimport --host <host_name>:<host_port> --db <database_name> --collection <collection_name> --file <path_to_dump_file> -u <my_user> -p <my_pass>
Assuming credentials needed, otherwise remove this option.
Solution 19 - Json
this will work:
$ mongoimport --db databaseName --collection collectionName --file filePath/jsonFile.json
