The Visual Geometry Group (VGG) at the University of Oxford released an open source annotation tool called VIA (VGG Image Annotator). It outputs its labels to CSV or JSON; Roboflow supports importing both and converting them to any other object detection format you like.
We also also have a full VGG Image Annotator tutorial covering how to label your object detection dataset.
Below, learn the structure of VGG Image Annotator CSV.

With Roboflow supervision, an open source Python package with utilities for completing computer vision tasks, you can merge and split detections in VGG Image Annotator CSV. Read our dedicated guides to learn how to merge and split VGG Image Annotator CSV detections.
Below, see model architectures that require data in the VGG Image Annotator CSV format when training a new model.
On each page below, you can find links to our guides that show how to plot predictions from the model, and complete other common tasks like detecting small objects with the model.
