反应中的 Xlsx sheetname 长度超过 31 个字符

Question

I'm using react to get table data from database and exporting it as excel and making the title of excel as tablename. But I'm facing and issue if the excel file name is exceeding 31 characters, sheet is not getting downloaded. And throwing below error in browser console output.

Uncaught Error: Sheet names cannot exceed 31 chars

Here is my code below

var workbook=XLSX.utils.book_new();
workbook.SheetNames.push(title); //title: tablename
var workSheet=XLSX.utils.aoa_to_sheet(tableData); //tableData: data from Database
workbook.Sheets[title]=workSheet;
var output=XLSX.write(workbook, {bookType:'xlsx', type:'binary'});
function s2ab(s) {
  var buf = new ArrayBuffer(s.length);
  var view = new Uint8Array(buf);
  for (var i=0; i!=s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
  return buf;
}
saveAs(new Blob([s2ab(output)], {type:"application/octet-stream"}), title + '.xlsx');

Edit: I don't want to change the sheetname. Just wanted react to download even if sheetnames exceeding 31 characters

Answer 1

Solved by doing following changes

var workbook=XLSX.utils.book_new();
//workbook.SheetNames.push(title); //title: tablename
var workSheet=XLSX.utils.aoa_to_sheet(tableData); //tableData: data from Database
//workbook.Sheets[title]=workSheet;
XLSX.utils.book_append_sheet(workbook, workSheet, "Test"); // This line solve the problem
var output=XLSX.write(workbook, {bookType:'xlsx', type:'binary'});
function s2ab(s) {
  var buf = new ArrayBuffer(s.length);
  var view = new Uint8Array(buf);
  for (var i=0; i!=s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
  return buf;
}
saveAs(new Blob([s2ab(output)], {type:"application/octet-stream"}), title + '.xlsx');
