Your task:
Look at the table image, determine the locations of the following cells. A cell's location MUST be represented as a json structure {'value': '<cell value>', 'location': (row_id, column_id)}, with row and column id beginning from 1. Some cell values may not be contained in this table. If so, represent their locations as 'DOES NOT EXIST'.
Target cells:
CELL VALUE 1: 'Attendance'
CELL VALUE 2: 'Guests: Lisa Steenson, Michael A. Stackpole'
CELL VALUE 3: '802'
CELL VALUE 4: 'March 20–23, 2014'
CELL VALUE 5: '1188'
CELL VALUE 6: 'N/A'
