docs: Tries to convert the value to number. Since we can not decide
  the type of the data coming back from the spreadsheet, we try to coerce it to number.
  Finally we check the coerced value whether is equals to the original value. This check assure that the coercion
  won't break anything. Note the 'weak equality' operator here is really important.
