Mongodb find to json8/10/2023 ![]() The below example shows that import the data into the Mongo_JSON_NEW collection from the MongoDB_JSON. ~]# mongoexport -collection=MongoDB_JSON -db=test -out=MongoDB_JSON. This data comes in a human-readable format. 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.

It is the plain text which was written in JavaScript object notation. DB parameter is used to import the data into a specified database collected from the file.The collection parameter is used to import the data into the specified collection from the file.The parameter mongoimport is used for import the JSON file data.In the above syntax, we are importing the JSON dump file into the specified collection.Mongoimport –collection = collection_name –db = db_name –username -password –file filename.JSON ![]() The filename is the name of the JSON dump file.Out parameter is the default that we need to use when exporting any collection in MongoDB.DB parameter is used to export the specified database collection into the file.Collection parameter is used to export the specified collection into the file.The parameter mongoexport is used to export the collection into the JSON file.In the above syntax, we are creating the dump file.
