How to get Webi Report data in JSON format

Hi,

Could you please suggest the options to export the WebI Report data in Json format.

I know using Report Elements you can export report data to JSON format.

I have multiple blocks in my Webi Report. Using report elements, I have to call api multiple times.

Is there way to export the Webi report data to JSON other than reporting elements option in single call to BOE

Please suggest
