Hey there Gabirella,
We have an app called EZ Exporter that lets you create custom CSV or Excel exports of your Shopify products and you can schedule an export to run automatically.
We have integrations with platforms/apps like Dropbox, Google Drive, Google Sheets, and Amazon S3 so a potential workflow is something like this:
With that said, we're not familiar with the Stileo platform so we're not sure whether our app can generate the CSV format required by them. If you like, you can reach out to us at firstname.lastname@example.org and if you can send us a sample CSV template from Stileo, we can take a look at it to see if our app can match their required format.
