Importing json from file into mongodb using mongoimport

Question

I have my json_file.json like this:

[
{
    \"project\": \"project_1\",
    \"coord1\": 2,
    \"coord2\": 10,
    \"status\": \"yes\",
    \"priority\": 7
}         


        

Answer 1

I faced opposite problem today, my conclusion would be:

If you wish to insert array of JSON objects at once, where each array entry shall be treated as separate dtabase entry, you have two options of syntax:

1. Array of object with valid coma positions & --jsonArray flag obligatory

   [
     {obj1},
     {obj2},
     {obj3}
   ]
   

2. Use file with basically incorrect JSON formatting (i.e. missing , between JSON object instances & without --jsonArray flag

   {obj1}
   {obj2}
   {obj3}
   

If you wish to insert only an array (i.e. array as top-level citizen of your database) I think it's not possible and not valid, because mongoDB by definition supports documents as top-level objects which are mapped to JSON objects afterwards. In other words, you must wrap your array into JSON object as ALAN WARD pointed out.
