I can't find a way to retrieve notes from a cell. I looked here:https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/get
I can update the note by using the code here: https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets/cells
... but I can't find a way to retrieve the note in the first place.
This the result of a values.get
call on a cell that has a note...
{u'range': u'Sheet1!D5', u'values': [[u'update CD data']], u'majorDimension': u'ROWS'}
as you can see, the notes to the cell are not there.
