Table:

cheeseburger	$4.56

bowl of tomato soup	$1.31

Given a table image and a set of target cells, your task is to identify their positions. Represent each cell's location as JSON in the format {'value': '<cell value>', 'location': (row number, column number)}, with both row and column number begin from 1.
Refer to the values below:
CELL VALUE 1: 'bag of potato chips'
CELL VALUE 2: '$1.31'
CELL VALUE 3: 'cheeseburger'
CELL VALUE 4: 'bowl of tomato soup'
CELL VALUE 5: '$4.56'
CELL VALUE 6: '$3.23'
CELL VALUE 7: 'slice of peach pie'
CELL VALUE 8: '$1.55'

Represent the location as 'DOES NOT EXIST' if a cell is not present in the table. 

The target cell locations are as follows:
CELL LOCATION 1: {'value': 'bag of potato chips', 'location': (4, 1)}
CELL LOCATION 2: {'value': '$1.31', 'location': (3, 2)}
CELL LOCATION 3: {'value': 'cheeseburger', 'location': (2, 1)}
CELL LOCATION 4: {'value': 'bowl of tomato soup', 'location': (3, 1)}
CELL LOCATION 5: {'value': '$4.56', 'location': (2, 2)}
CELL LOCATION 6: {'value': '$3.23', 'location': (1, 2)}
CELL LOCATION 7: {'value': 'slice of peach pie', 'location': (1, 1)}
CELL LOCATION 8: {'value': '$1.55', 'location': (4, 2)}
