I have created a new Google Sheet on Dropbox. How to get data from this sheet via API?

Hi jayeshbhatia,

Handling the content of any file (either downloadable or exportable) is your responsibility. There are no API (provided by Dropbox) to do that, but you can use suitable third party software (library) or implement the handling yourself.

jayeshbhatia You can export a Google Sheet from Dropbox using /2/files/export. (That's a link to the documentation for the HTTPS endpoints themselves, but we recommend using one of the official SDKs if possible. Those have corresponding native methods for the HTTPS endpoints.)

As Здравко said though, reading/parsing specific data from that result is up to you.
