We can import the data into the collection from JSON file using mongoimport we can also export the collected data into the JSON file using mongoexport. They have their multiple data types are available in MongoDB using this datatype, we can insert the data into the collection. Json ~]# mongoimport -db test -collection Mongo_JSON_NEW -file ~]# mongo The below example shows that import the data into the Mongo_JSON_NEW collection from the MongoDB_JSON. This data comes in a human-readable ~]# mongoexport -collection=MongoDB_JSON -db=test -out=MongoDB_JSON. Json file.Īfter exporting the data into the JSON file, we can see this file using the cat command. Thus, the Emp_id attribute shows the field, and 101 integers are shown the value of a field.īelow example shows export MongoDB_JSON collection into the MongoDB_JSON. In the below example, we have inserted the numeric value emp_id as 101 into the MongoDB_JSON collection. Insert the data using numeric data types. Thus, the name attribute shows the field, and the ABC string shows the value of the field. In the below example, we have inserted the string value name as ABC into the MongoDB_JSON collection. Examples of MongoDB JSONĭifferent examples are mentioned below: Example #1 We can directly start our development without creating any structure. Using it, we have no need to create the structure of documents for the database. Basically, documents are polymorphic the fields can vary from one document to another within the same collection. It provides a flexible database and schema design as compared to the tabular data model, which was used in relational database models. ![]() Thus, humans and machines both understand and read the data of files. It is basically used the alternate of an XML, which is the language-independent data format. The important function of JSON is to transmit the data between web applications and servers. It makes the notation of key-value pair using strings, and it will easily be exported and imported into the various tools. The use of JSON in MongoDB is very easy also, we can use the JavaScript built-in function to convert the JSON strings into the object of JavaScript’s.īelow data type is supported by MongoDB JSON: We can use it to send the data between one computer to another computer. ![]() It is the plain text which was written in JavaScript object notation.
