# File Transformer
Allows you to write a custom implementation of some features in Datasaur.
File transformer feature can be found in **Team workspace**. You can hover over to the left sidebar and click **File Transformer**.
Click **Create file transformer** to start writing your script. Enter a name, then choose the type of file transformer:
* Select **Import** to create a script for importing files into a project.
* Select **Export** to create a script for exporting files from a project.
### External dependencies
Datasaur no longer support importing external dependencies. To make use of common helpers, embed the relevant code snippets directly in your file transformer.
