Excel列信息

js代码如下：

 var X = XLS;
 function to_json(workbook) {
     var result = {};
     workbook.SheetNames.forEach(function (sheetName) {
         var roa = XLS.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
         if (roa.length > 0) {
             result[sheetName] = roa;
         }
     });
     return result;
 }

 function fixdata(data) {
     var o = "", l = 0, w = 10240;
     for (; l < data.byteLength / w; ++l) o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w, l * w + w)));
     o += String.fromCharCode.apply(null, new Uint8Array(data.slice(l * w)));
     return o;
 }

 function process_wb(wb,type) {
     var output = "";
     switch (type) {
         case "json":
             output = JSON.stringify(to_json(wb), 2, 2);
             break;
         case "form":
             output = to_formulae(wb);
             break;
         default:
             output = to_csv(wb);
     }
     //if (out.innerText === undefined) out.textContent = output;
     //else out.innerText = output;
     return output;
 }
