Hi Paula to export a document as a VDX file open the document and navigate to File > Download As > Visio (VDX). Your document will download as a VDX file to your local device.

Thanks but I need to export it as a VDS file :(

Megan could you help me with that file extension please? VSD

Hey Paula apologies for the confusion. This is currently not available in Lucidchart. 

Oh no!!

Do you know how can I resolve it?

Ho Paula Lucidchart only supports VDX export at this time. If VSD export is something you'd like to see in our product please fill out this feature request form. We're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that.
