Mongoimport import json array as collection not as key in collection

Question

I am attempting to seed a database with a json array of data with mongoimport, however when the data reaches the mongo collection, it imports as a key in the collection object like this:

"items" is my json file, it always shows up as "items", I want the parent array to be the array I'm trying to import itself, does this make sense?

Update

Please see this example, the first image is how mongoimport is importing this array of objects:

{ "_id" : ObjectId("58dc01ecec116d4c9039e47c"), "items" : [ { "id" : 1, "_id" : "item1", "type" : "alert", "title" : "hello.world", "email" : "[email protected]", "message" : "", "createdDate" : "date", "price" : "$9.00", "active" : true }, { "id" : 2, "_id" : "item2", "type" : "welcome.lol", "title" : "Item 2", "email" : "[email protected]", "message" : "lol", "createdDate" : "date", "price" : "$12.00", "active" : true }, { "id" : 3, "_id" : "item3", "type" : "message", "title" : "various.domain", "email" : "[email protected]", "message" : "lol", "createdDate" : "date", "price" : "$3.00", "active" : false }, { "id" : 4, "_id" : "item4", "type" : "message", "title" : "something.else", "message" : "", "createdDate" : "date", "price" : "$12.00", "active" : false }, { "id" : 5, "_id" : "item5", "type" : "update", "title" : "wow.lol", "email" : "[email protected]", "message" : "", "createdDate" : "date", "price" : "$12.00", "active" : false }, { "id" : 6, "_id" : "item6", "type" : "update", "title" : "domainname.net", "email" : "[email protected]", "message" : "cars", "createdDate" : "date", "price" : "$12.00", "active" : false }, { "id" : 7, "_id" : "item7", "type" : "update", "title" : "something.lol", "email" : "[email protected]", "message" : "", "createdDate" : "date", "price" : "$12.00", "active" : false } ] }

Notice how its treats the entire array as an "item" object, with a key in the item "items" which is the array, I want the data to look like this:

{ "_id" : ObjectId("58dc027a2c74df002a957281"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:42.227Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027b2c74df002a957282"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:43.574Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027b2c74df002a957283"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:43.708Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027b2c74df002a957284"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:43.855Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027b2c74df002a957285"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:43.994Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027c2c74df002a957286"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:44.128Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027c2c74df002a957287"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:44.263Z"), "active" : true, "__v" : 0 }
{ "_id" : ObjectId("58dc027c2c74df002a957288"), "price" : "asdf", "message" : "asdf", "email" : "aasfd", "title" : "asdf", "dateCreated" : ISODate("2017-03-29T18:52:44.391Z"), "active" : true, "__v" : 0 }

Where each item in the array is created as an "item" in mongo, each with its own ObjectID - otherwise it's useless for CRUD applications.

It would be useful to know what command you are using to import, but I just created a database an imported the following JSON with this command:

mongoimport --db test --collection example --type json --file example.json --jsonArray

Make sure you are using the --jsonArray flag
