Can you define multiple ranges in the utility functions?

For example: ws['!ref'] = "D1:E5,B12:D18"

You want the second approach:

var XLSX = require('xlsx');
var wb = XLSX.readFile('WLAC-CurricStrengthening-Film.xlsx');
var ws = wb.Sheets['Local Share LMI'];

/* first part */
ws['!ref'] = "D1:E5"; // change the range to the first block
var o1 = XLSX.utils.sheet_to_json(ws);

/* second part */
ws['!ref'] = "B12:D18"; // change the range to the second block
var o2 = XLSX.utils.sheet_to_json(ws);

var output = o1.concat(o2);

And output is:

[
  { 'TOP Code(s)': '61220', 'Program Title': 'Film Production' },
  { 'TOP Code(s)': '614', 'Program Title': 'Graphics and Digital Imagry' },
  { 'SOC Code': '274011', 'Occupational Title': 'Audio/Video Equipment Technicians', 'Annual Openings': '914' },
  { 'SOC Code': '499096', 'Occupational Title': 'Riggers', 'Annual Openings': '67' },
  { 'SOC Code': '393092', 'Occupational Title': 'Costume Attendants', 'Annual Openings': '218' },
  { 'SOC Code': '274032', 'Occupational Title': 'Film and Video Edior', 'Annual Openings': '910' },
  { 'SOC Code': '271027', 'Occupational Title': 'Set and Exhibit Designers', 'Annual Openings': '222' },
  { 'SOC Code': '472141', 'Occupational Title': 'Painters, Construction, Matinenance', 'Annual Openings': '1658' }
