Relationship between Zoho Project and Zoho Sheet

Relationship between Zoho Project and Zoho Sheet

Hi,

I have been able to implement fully the Document Content API to interact with spreadsheets stored in Zoho Sheet from my desktop application. Is it possible to similarly interact with a spreadsheet stored in Zoho Projects via the Document Content API. If so how. If not is there another way or is there a way that my application can get Zoho to copy the spreadsheets from Projects to Sheet. If so how?

With regard to Projects I can download spreadsheets via the Download API but I cannot access the data directly from my application as I can in Sheet.
