Importing LabelBox JSON Output to TensorFlow

I'm working on an object detection model using TensorFlow and the Keras package. My first iteration did not provide great results, so I am now using LabelBox to draw bounding boxes around my images. LabelBox outputs one JSON file with all the images and labels, in a format like below. I'm trying now to import the labeled data, but can't find a good solution to doing so. I researched that I may need to convert the JSON to a TFRecord, but have not been able to find a clean script to do so. I am relatively new to python and machine learning, so any help would be greatly appreciated.

LabelBox OutputJson:

I was looking for a similar solution. What worked well for me was utilizing Roboflow. I made a free account and was able to convert LabelBox JSON output to TFRecords for model training. https://roboflow.com/convert/labelbox-json-to-tensorflow-tfrecord
