Is there any way to download an isheet (displaydata only or xlsx/csv file)?

I see that you can use the api/13/isheet/{isheetid}/items, but I'm wondering if it is an easier way to only get the "displaydata" of the isheet as a response or an xlsx file download?

The API call mentioned above gives all the data where you have to pick out the values and structure it afterwards.

Can't seem to find any API calls that does this.
