Hello, I'm a beginner and I don't understand how can I create an xlsm file with this code. I try to change this line : XLSX.writeFile(wb, 'test.xlsx') by this one : XLSX.writeFile(wb, 'test.xlsm') but it doesn't work.

Could you help me ?
Thanks !

`var XLSX = require('XLSX')

/function datenum(v, date1904) {
if(date1904) v+=1462;
var epoch = Date.parse(v);
return (epoch - new Date(Date.UTC(1899, 11, 30))) / (24 * 60 * 60 * 1000);
}
/

function sheet_from_array_of_arrays(data, opts) {
var ws = {};
var range = {s: {c:1, r:1}, e: {c:0, r:0 }};
for(var R = 0; R != data.length; ++R) {
for(var C = 0; C != data[R].length; ++C) {
if(range.s.r > R) range.s.r = R;
if(range.s.c > C) range.s.c = C;
if(range.e.r < R) range.e.r = R;
if(range.e.c < C) range.e.c = C;
var cell = {v: data[R][C] };
if(cell.v == null) continue;
var cell_ref = XLSX.utils.encode_cell({c:C,r:R});

		if(typeof cell.v === 'number') cell.t = 'n';
		/*else if(typeof cell.v === 'boolean') cell.t = 'b';
		else if(cell.v instanceof Date) {
			cell.t = 'n'; cell.z = XLSX.SSF._table[14];
			cell.v = datenum(cell.v);
		}
		else cell.t = 's';*/
		
		ws[cell_ref] = cell;
	}
}
if(range.s.c < 1) ws['!ref'] = XLSX.utils.encode_range(range);
return ws;

}

/* original data */
var data = 1,2,3
var ws_name = "SheetJS";

Suppose you had your data:

var data = [
  ["col A", "col B", "col C"],
  [1,2,3],
  ["foo", "bar", "baz"]
]

Then the following will generate an XLSM workbook:

// var XLSX = require('xlsx'); // <-- uncomment this in node
var wb = {SheetNames:["Sheet1"], Sheets:{Sheet1:XLSX.utils.aoa_to_sheet(data)}};

To actually distribute the file, use one of the techniques outlined in the README. For example, you can use writeFile in node:

XLSX.writeFile(wb, 'test.xlsm');

Please follow up if you have any other questions.
