This toolkit is designed to help you convert datasets in [JSON](https://www.ultralytics.com/glossary/json) format, particularly those following the [COCO (Common Objects in Context)](https://cocodataset.org/#home) standards, into the [YOLO format](https://docs.ultralytics.com/datasets/#yolo-format). The YOLO format is widely recognized for its efficiency in [real-time](https://www.ultralytics.com/glossary/real-time-inference) [object detection](https://docs.ultralytics.com/tasks/detect/) tasks.\n\nThis conversion process is essential for [machine learning](https://www.ultralytics.com/glossary/machine-learning-ml) practitioners looking to train object detection models using frameworks compatible with the YOLO format, such as [Ultralytics YOLO](https://docs.ultralytics.com/models/yolo11/). Our code is flexible and designed to run across various platforms including Linux, macOS, and Windows.\n\n[![Ultralytics Actions](https://github.com/ultralytics/JSON2YOLO/actions/workflows/format.yml/badge.svg)](https://github.com/ultralytics/JSON2YOLO/actions/workflows/format.yml)\n[![Ultralytics Discord](https://img.shields.io/discord/1089800235347353640?logo=discord\u0026logoColor=white\u0026label=Discord\u0026color=blue)](https://discord.com/invite/ultralytics)\n[![Ultralytics Forums](https://img.shields.io/discourse/users?server=https%3A%2F%2Fcommunity.ultralytics.com\u0026logo=discourse\u0026label=Forums\u0026color=blue)](https://community.ultralytics.com/)\n[![Ultralytics Reddit](https://img.shields.io/reddit/subreddit-subscribers/ultralytics?style=flat\u0026logo=reddit\u0026logoColor=white\u0026label=Reddit\u0026color=blue)](https://reddit.com/r/ultralytics)\n\n## ⚙️ Requirements\n\nTo get started with JSON2YOLO, you'll need a [Python](https://www.python.org/) environment running version 3.8 or later. Additionally, you'll need to install all the necessary dependencies listed in the `requirements.txt` file. You can install these dependencies using the following [pip](https://pip.pypa.io/en/stable/) command in your terminal:\n\n```bash\npip install -r requirements.txt # Installs all the required packages\n```\n\n## 💡 Usage\n\nTo convert your COCO JSON dataset to YOLO format, run the `convert.py` script from your terminal. You need to specify the path to the directory containing your COCO JSON annotation files and the directory where you want to save the resulting YOLO label files.\n\n```bash\n# Example usage: Convert COCO annotations to YOLO format\npython convert.py --json_dir path/to/coco/annotations --save_dir path/to/yolo/labels\n```\n\n- `--json_dir`: Path to the directory containing COCO JSON annotation files (e.g., `instances_train2017.json`).\n- `--save_dir`: Path to the directory where the converted YOLO label files (`.txt`) will be saved.\n\nThis script will process the JSON files, extract bounding box information, and convert it into the YOLO format, saving one `.txt` file per image in the specified save directory. For more details on [dataset formats](https://docs.ultralytics.com/datasets/), refer to our documentation.\n\n## 📚 Citation\n\nIf you find our tool useful for your research or development, please consider citing it:\n\n[![DOI](https://zenodo.org/badge/186122711.svg)](https://zenodo.org/badge/latestdoi/186122711)\n\n## 🤝 Contribute\n\nWe welcome contributions from the community!
