I have json data and i want to import in neo4j.
Export data option will be there in neo4j but how to import JSON data in neo4j.
This is the link of jsfiddle. http://jsfiddle.net/harmeetsingh090/mkdm4t44/
Please help if someone know.
You can use jq to manipulate your data into CSV format and then use the LOAD CSV command.
Neo4J doesn't have a native way of doing this, but there is a plugin for Neo4J called apoc.load.json. You can load data doing the following:
CALL apoc.load.json("file:///<path_to_file>/example.json") YIELD value as document
UNWIND document.root AS root
MERGE (e:ExampleNode {id: root.id})
...
You can find more information on the plug here: https://neo4j-contrib.github.io/neo4j-apoc-procedures/. I've recently used this and found it to be quite intuitive.

I wanted to import data to my collection in mongodb atlas, and I was following the documentation: https://docs.mongodb.com/compass/beta/import-export/ but there is no "ADD DATA" and I don't know if Im using some other version or Im doing something else wrongly.
I need to import whole file which is json array.
The docs you referenced are for a future version of Compass. If you want to import from EJSON at the command line you can use mongoimport.
Here's the simplest syntax, but there are many variations possible.
mongoimport --db=users --collection=contacts --file=contacts.json
I have noticed there is a feature in web interface of ArangoDB which allows users to Download or Upload data as JSON file. However, I find nothing similar for CSV exporting. How can an existing Arango DB collection be exported to a .csv file?
If you want to export data from ArangoDB to CSV, then you should use Arangoexport. It is included in the full packages as well as the client-only packages. You find it next to the arangod server executable.
Basic usage:
https://docs.arangodb.com/3.4/Manual/Programs/Arangoexport/Examples.html#export-csv
Also see the CSV example with AQL query:
https://docs.arangodb.com/3.4/Manual/Programs/Arangoexport/Examples.html#export-via-aql-query
Using an AQL query for a CSV export allows you to transform the data if desired, e.g. to concatenate an array to a string or unpack nested objects. If you don't do that, then the JSON serialization of arrays/objects will be exported (which may or may not be what you want).
The default Arango install includes the following file:
/usr/share/arangodb3/js/contrib/CSV_export/CSVexport.js
It includes this comment:
// This is a generic CSV exporter for collections.
//
// Usage: Run with arangosh like this:
// arangosh --javascript.execute <CollName> [ <Field1> <Field2> ... ]
Unfortunately, at least in my experience, that usage tip is incorrect. Arango team, if you are reading this, please correct the file or correct my understanding.
Here's how I got it to work:
arangosh --javascript.execute "/usr/share/arangodb3/js/contrib/CSV_export/CSVexport.js" "<CollectionName>"
Please specify a password:
Then it sends the CSV data to stdout. (If you with to send it to a file, you have to deal with the password prompt in some way.)
I see we can import json files into firebase.
What I would like to know is if there is a way to import CSV files (I have files that could have about 50K or even more records with about 10 columns).
Does it even make sense to have such files in firebase ?
I can't answer if it make sense to have such files in Firebase, you should answer that.
I also had to upload CSV files to Firebase and I finally transformed my CSV into JSON and used firebase-import to add my Json into Firebase.
there's a lot of CSV to JSON converters (even online ones). You can pick the one you like the most (I personnaly used node-csvtojson).
I've uploaded many files (tab separated files) (40MB each) into firebase.
Here are the steps:
I wrote a Java code to translate TSV into JSON files.
I used firebase-import to upload them. To install just type in cmd:
npm install firebase-import
One trick I used on top of all the one already mentioned is to synchronize a google spreadsheet with firebase.
You create a script that upload directly to firebase db base on row / columns. It worked quite well and can be more visual for fine tuning the raw data compared to csv/json format directly.

Here is the fastest way to Import your CSV to Firestore:
Create an account in Jet Admin
Connect Firebase as a DataSource
Import CSV to Firestore
Ref:

To create a native backup and restore it, one has to use arangodump and arangorestore.
To import from JSON (and CSV, TSV), one has to use arangoimp.
What can I use to export to JSON from ArangoDB?
One possibility is to use the arangodump tool that is shipped with ArangoDB.
It can be used to dump an entire database or individual collections. It stores dumped data in JSON format on disk.
Maybe arangodump's output already is in a format that you can work with.
As the title goes , I wonder if MongoDB has a data file format to import directly ?I know that mysql has "sql" file format for it to import directly .I am now in a project has the same requirement.Any one can tell me ?
MongoDB can import data using the mongoimport tool from JSON, CSV and TSV data format as you can see here
MongoDB internally represents data as a binary-encoded JSON (BSON), so importing and exporting in JSON format is really fast and intuitive
Of course.Mongodb use mongodump/mongoexport to export the data to outside files and use mongorestore/mongoimport to import data to its databases.more details , just reference to mongodb doc.mongodump and mongoexport ,mongorestore and mongoimport ,do have some differences .More details ,please refer to mongodb doc.
