# Export Versions

You can export data from BinaExpert at any time. You can export data using the BinaExpert web interface or our Python package.

To export data, first generate a dataset version in the BinaExpert dashboard. You can do so on the "Versions" page associated with your project.

**When a version of a dataset is created, a complete freeze of categories, images, and all configurations that existed at that moment remains intact, even if you delete all the images or change the configurations. In other words, your version always represents the latest update of your dataset.**

After you have generated a dataset, click "Export" next to your dataset version:

You can download your data in a wide variety of formats. You can see a full list of supported export formats in the "Export" tab of our formats directory.

### Class Name Sanitization

To prevent issues from arising during training, we sanitize class names both at upload/import and export. At export, we perform the following:

* Class names are converted to ASCII
  * Where possible, characters are anglicized (ex:  `ü` to `u`)
  * Otherwise, they are replaced with a dash (`-`)
