imagedownload - Retrieve images in cells using Google Sheets API

Question

I'm using the Google Sheets API to return the JSON of a Google Sheet,

e.g

 var url = 'https://spreadsheets.google.com/feeds/list/' + id + '/od6/public/values?alt=json';

In one of the cells I have added an image, but this appears empty in the json.
How can I retrieve this image?

Answer 1

This is possible if you use Sheets API v4. If you make a spreadsheets.get request you get access to the =IMAGE(...) formula used in the cell.

GET https://sheets.googleapis.com/v4/spreadsheets/{SPREADSHEET_ID}?
    includeGridData=true&ranges={RANGE_A1}&
    fields=sheets%2Fdata%2FrowData%2Fvalues%2FuserEnteredValue

          ]
