Exporting Annotations

Overview of exporting annotations from Ango Hub

Administrators and project managers can create and download an export of all annotations performed in a project on Ango Hub.

Getting your Export

Enter your project's Export tab. The Export button at the bottom will allow you to download your annotations.

You will receive a notification within Ango Hub when the export is ready. You may navigate away from the page while the export is being prepared.

Export Options

Export Format

You can download your export in the JSON, NDJSON, and YOLO formats.

If you need to download your export in more, different formats, we recommend you use our Export Converter Plugins.

We have developed the JSON export format to be as easy to parse and convert to other formats as possible. If you need your annotations in a format that is not supported by our plugins and you are a paid customer, contact us and we will provide you a script to convert our JSON export to the format of your choice.
