  # local game data (windows)
  dotnet charon DATA IMPORT --dataBase "c:\my app\gamedata.json" --schemas Character --input "c:\my app\characters.json" --inputFormat json --mode safeUpdate
  
  # remote game data
  dotnet charon DATA IMPORT --dataBase "https://charon.live/view/data/My_Game/develop/" --schemas Character --input "./characters.json" --inputFormat json --mode safeUpdate --credentials "<API-Key>"

--dataBase
   Absolute or relative path to game data. Use quotation marks if your path contains spaces.

   .. code-block:: bash
   
     # local file
     --dataBase "c:\my app\gamedata.json"
     
     # remote server
     --dataBase "https://charon.live/view/data/My_Game/develop/"

--credentials
   The API key used to access remote server in case of *--dataBase* being URL.

--schemas
   A list of types of documents (schemas) to import. By default all schemas *EXCEPT* metadata are imported.
       
   - Use space to separate multiple schemas.
   - You can use wildcards (*) at the beginning and end of names.
   - You can use identifiers in {} instead of names.
   - You can exclude certain names by using an exclamation mark (!) at the beginning of their names.

   .. code-block:: bash
   
     # schema name
     --schemas Character

     --schemas Char* !Character
     --schemas !*Item*
     
     # excluding system schemas (Schema, SchemaProperty, ProjectSettings)
     --schemas ![system]
     
--mode
   Import mode controls merge behavior during import.

.. _CommandLine_Import_Structure:
---------------------
 Input Data Structure
---------------------

The data you input should follow this structure (recommended):

   .. code-block:: js
     
     {
       "Collections": {
         "<Schema-Name>": [
           {
             // <Document>
           }
         ]
       }
     }
     
This structure is also accepted:

   .. code-block:: js
     
     {
       "<Schema-Name>": [
         {
           // <Document>
         }
       ]
     }
     
A list of documents is accepted if only one name in ``--schemas`` is specified:

   .. code-block:: js
   
     [
       {
         // <Document>
       }
     ]
     
And single document is accepted too if only one name in ``--schemas`` is specified:

   .. code-block:: js
   
     {
       // <Document>
     }
