I am a beginner and trying to import data from MongoDB. The Robo3T which I use for visualization shows something like below.
--Kins
Kins
And this is the command I use
mongoexport --db kins --collection test --out output.json
mongoexport --db kins.kins --collection test --out output.json
mongoexport --db [kins].[kins] --collection test --out output.json
But none of them work. What's the correct syntax?
How to import data in json format. Please guide me.
Link I reviewed:
Dump Mongo Collection into JSON format
I guess you want to use the --jsonArray (docs) flag because by default mongoexport writes data using one JSON document for every MongoDB document.
mongoexport --db kins.kins --collection test --out output.json --jsonArray
You can consider using the --pretty (docs) flag too. It will output documents in pretty-printed format.
It is the first time I use mongodb.
I want to insert a zip.json file into mongodb running one of the commands bellow, and I get error.
mongoimport --db test --collection zips --file \C:\Install\advanced programs\mongodb\zips.json
mongoimport --db test --collection zips --type json --file \C:\Install\advanced programs\mongodb\zips.json
The error:
To run these commands I oppened a cmd in bin directory of mongodb and I ran mongo.
you should use double quotation "" for file path because your file path contained space and no need to extra back slash \C:\ just use C:\
use
mongoimport --db test --collection zips --file "C:\Install\advanced programs\mongodb\zips.json"
instead of
mongoimport --db test --collection zips --file \C:\Install\advanced programs\mongodb\zips.json
Perhaps your json is not valid? Looks like there is an extra quote somewhere. Try validating it using any online service.
You need to start different cmd and go to C:\Program Files\MongoDB\Server\3.2\bin or it should be in ur path and then u need to run "mongoimport" command. If you start using "mongoimport" from "mongo" shell then it will not work.
I'm using this command
mongoimport --db test --collection bankdata --drop --file bank_data.json --port 27017 --host 127.0.0.1
to import a json file, but when I do it I get this message
Failed: error unmarshaling bytes on document #0: JSON decoder out of sync - data changing underfoot?
2016-05-24T08:00:31.552-0600 imported 0 documents
You are trying to import json array ,so you need to add --jsonArray option according to documentation https://docs.mongodb.com/manual/reference/program/mongoimport/
mongoimport --jsonArray --db test --collection bankdata --drop --file
bank_data.json
I have a lot of json files in archive and i need to import them into mongo per one operation (i think that it might be in cycle). Have you any ideas about this?
If you are in a Linux/Unix shell you can try
for filename in *; do mongoimport -d mydb -c $filename; done
If you are on Windows:
FOR %i IN (C:\mongodbData\*.json) DO mongoimport --db dbName --collection colection --type json --file %i
mongorestore is import all exported mongodb files
cd C:\Program Files\MongoDB\Server\4.0\bin
mongorestore.exe -d <db name> C:\Users\Mike\Downloads\myProject\
But if you really want to import all only meta json files without .bson
cd C:\Users\Mike\Downloads\myProject\
FOR %i IN (*.json) DO "C:\Program Files\MongoDB\Server\4.0\bin\mongoimport.exe" --db <db name> --collection %~ni --type json --file %i
This is sample work on windows 10
You need to use mongorestore for recovery from dump, created by the mongodump
http://docs.mongodb.org/v2.6/reference/program/mongorestore/
for example
mongorestore --drop --oplogReplay mongodb/
You can use this:
FOR %i IN (<data folder>\*.json) DO mongoimport -d <database> -c <collection> --file %i
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"),

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:

I do not know what the problem is. Can someone recommend a solution?
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.
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",

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.
console:
mongoimport -d dbName -c collectionName dataFile.js
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
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.
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
Run the import command in another terminal. (not inside mongo shell.)
mongoimport --db test --collection user --drop --file ~/downloads/user.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
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:-
mongoimport --db databaseName --collection tableName --file filepath.json
Example:-
Place your file in admin folder:-
C:\Users\admin\tourdb\places.json
Run this command on your teminal:-
mongoimport --db tourdb --collection places --file ~/tourdb/places.json
Output:-
admin#admin-PC MINGW64 /
$ mongoimport --db tourdb --collection places --file ~/tourdb/places.json

I tried something like this and it actually works:
mongoimport --db dbName --file D:\KKK\NNN\100YWeatherSmall.data.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"
}
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.
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
mongoimport -d <dbname> -c <collectio_name> --file <c:\users\test.json> --jsonArray
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.
this will work:
$ mongoimport --db databaseName --collection collectionName --file filePath/jsonFile.json
