I'm using Drupal 7 and I've created a content type as 'CONTENT_TABLE', which includes multiple fields (COLUMNS) as such: CONTENT_ID, CONTENT_NAME, LARGE_THUMBNAIL, ZIP_FILE...

I want to export the data (each row of the table) into a JSON. I need to use this JSON as an input for another website. 

I have tried to look for [Node export][1] module, but I'm not sure how to export the data into JSON which can be used as is. 

Expected JSON:

    {
       "ContentItems": [
          {
             "CONTENT_ID": "123",
             "CONTENT_NAME": "ABC",
             "LARGE_THUMBNAIL": "C:/LargeThumbnail/ABC.jpg",
             "ZIP_FILE": "C:/LargeThumbnail/ABC.zip"
          },
          {
             "CONTENT_ID": "234",
             "CONTENT_NAME": "PQR",
             "LARGE_THUMBNAIL": "C:/LargeThumbnail/PQR.jpg",
             "ZIP_FILE": "C:/LargeThumbnail/PQR.zip"
          }
       ]
    }
