How To Convert VGG Image Annotator JSON to YOLOv4 PyTorch TXT

In this guide, we show you how to convert data between the

and

formats for free. You can use your converted data to train

models and other models that support the

format.
‍

Step 1: Create a free Roboflow public workspace

Roboflow is a universal conversion tool for computer vision annotation formats. The Public plan is the best way for those exploring personal projects, class assignments, and other experiments to try Roboflow. To convert your dataset, start by creating a free workspace on the Public plan.
‍

Step 2: Upload your data into Roboflow

Once your account has been created, click Create New Project.

Upload your data to Roboflow by dragging and dropping your

VGG Image Annotator JSON

images and annotations into the upload space.

Learn more about how to create these annotations for your object detection dataset in our VGG Image Annotator tutorial.

Step 3: Generate Dataset Version

Next, click "Generate New Version" to generate a new version of your dataset:

You can then apply any preprocessing or augmentation steps to your dataset:

Step 4: Export Dataset Version

Congratulations, you have successfully converted your dataset from

VGG Image Annotator JSON

format to

YOLOv4 PyTorch TXT

format!

VGG Image Annotator JSON

data into the

YOLOv4 PyTorch TXT

format on the Roboflow platform.
‍

How long does it take to convert

VGG Image Annotator JSON

data to

YOLOv4 PyTorch TXT

?
‍

If you have between a few and a few thousand images, converting data between these formats will be quick. But, the time it takes to convert between data formats increases with the more images you have.
