title: Defining a js-xlsx cell range
body: <p>I'm trying to read excel values using js-xlsx</p>
  
  <p>I'm able to get a cell value from a workbook sheet using the following code</p>
  
  <pre><code>if(typeof require !== 'undefined') XLSX = require('xlsx');
  var workbook = XLSX.readFile('test.xls');
  var sheet_name_list = workbook.SheetNames;
  var sheet = sheet_name_list.indexOf('sheet_name');
  var sheetF48 = workbook.Sheets[sheet_name_list[sheet]]['F48'].v;
  </code></pre>
  
  <p>What I would like to do next is define a cell range so only those cell values are returned. I have figured out to get a sheet's ref by:</p>
  
  <pre><code>var sheet1 = workbook.Sheets[sheet_name_list[sheet_name]]
  var range = XLSX.utils.decode_range(sheet1['!ref']);
  </code></pre>
  
  <p>Is it possible to define a cell range by providing the cell references?</p>
