When determining the number format, do not consider characters that have been escaped. For example, a number format like this: #,##0" W/m2" Should not be interpreted as an "n_date" column just because it contains the character "m". This implements a simple solution, where if the format string contains an double-quote after the search string, it does not match. Check the regex for the "M" (month) regex here. A more robust regex is described here A better solution would be to not use regex here at all but something more along the lines of how numberFormatStandardized() reads through the string.
