# Upload File Transformer

To create a file transformer, you can also upload an existing script. Only files with `.js`, `.ts`, and `.txt` extensions are supported.

Use the **Upload** button on the right side of the editor to upload the file.

After uploading, the current file transformer will be replaced with the newly updated version.
