string->cell
(define (string->cell s)
(error 'not-yet-implemented))
- if s is the empty string, evaluate to void
- if s represents a number, evaluate to that number
- if s starts with "(" and ends with ")", evaluate to a form suited for eval
- otherwise, evaluate to s
csv->spreadsheet
(define (csv->spreadsheet matrix)
(error 'not-yet-implemented))
given a list of lists of strings, evaluate to a list of list of cells using #string->cell and a couple of list higher order functions.
row-count
(define (row-count sheet)
(error 'not-yet-implemented))
