Unable to parse array of strings without quotes

Excellent tool. I had used it a year ago. Now the same XLSX file does not parse due to lack of quotes in the string-array fields. Is there a config-option to make it backward compatible?

./export.sh 
parsing excel: myXLSfile.xlsx
  * sheet:  sheetName
undefined:1
([a,b,c])
  ^

ReferenceError: a is not defined

really sorry for that， it's a break update and cannot make it backward compatible for now.
array should be like this ["a","b","c"] now.
