How to import annotations to a Hasty project?

Since our Import annotations feature is in Beta, Hasty allows you to import labels in a JSON file with a special structure of the Hasty JSON v1.1. It uses a format similar to COCO but builds on top of it to add some complexity. So, to avoid potential errors when uploading your annotations, please follow these simple steps:

1. Create your Hasty project and upload all the necessary files to it;
2. Create the label classes and attributes you will use in your project;
3. Download the project to your local machine using the Export data feature. When choosing the export format, please select Hasty JSON v1.1. As a result, you will get a JSON file that will already contain all the necessary information about your project, images, label classes, and attributes;
4. Add your annotations to the JSON file. Please check out simple examples and the annotations' import types supported by Hasty;
5. Upload the JSON file to your project through the Import Annotations (Beta) feature.

Awesome, you’ve nailed it!
