将HTML表导出到Excel时编码UTF-8

Encoding UTF-8 when exporting HTML table to Excel

本文关键字：Excel 编码 UTF-8 HTML      更新时间：2023-09-26

我正在尝试使用javascript将HTML表导出到Excel。这是javascript代码

<script type="text/javascript">
    var tableToExcel = (function() {
          var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function(s, c) { return s.replace(/{('w+)}/g, function(m, p) { return c[p]; }) }
          return function(table, name) {
            if (!table.nodeType) table = document.getElementById(table)
            var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
            window.location.href = uri + base64(format(template, ctx))
          }
        })()
</script>

这是我的头

<meta http-equiv="content-type" content="application/vnd.ms-excel;" charset="UTF-8">
<meta charset="UTF-8">

这是我的桌子

<table id="tblExport">
   <tr>
      <td>José</td>
      <td>María</td>
   </tr>
</table>

这是触发导出的按钮

<input type="button" onclick="tableToExcel('tblExport', 'W3C Example Table')" value="Export to Excel">

我无法正确导出UTF-8字符，比如é或í。我尝试将HTML表作为UTF8导入OO Calc，而不转换为实体，但不起作用。我有MS Excel 2010和Win7 64位。

如何正确导出UTF-8字符？

谢谢！

首先：您的标头格式不正确。应该是：

<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">

第二：它应该在你的模板中，因为它包含Excel的字符集信息。

<script type="text/javascript">
    var tableToExcel = (function() {
          var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function(s, c) { return s.replace(/{('w+)}/g, function(m, p) { return c[p]; }) }
          return function(table, name) {
            if (!table.nodeType) table = document.getElementById(table)
            var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
            window.location.href = uri + base64(format(template, ctx))
          }
        })()
</script>

您可以在内容字符串前面加上UTF-8 BOM定义：

function ExportToExcel() {
    var BOM = "'uFEFF";
    var htmltabel = document.getElementById("tabella_finale");
    var html = htmltabel.outerHTML;
    window.open('data:application/vnd.ms-excel,'+ encodeURI(BOM + html));
}

如果您想根据@Axel Richter的答案更改默认文件名，请尝试以下操作：

var link = document.createElement('a');
link.download = 'filename.xls';
...
link.href = uri + base64(format(template, ctx));
link.click();
...

用链接替换window.location.hf。href

function exportData(report_id){
    var blob = new Blob([document.getElementById(report_id).innerHTML], {
        type: "text/plain;charset=utf-8;"
    });
    saveAs(blob, "Report.xls");
}

将表数据作为纯文本并保存为Excel，而不会出现编码问题

我将再次引用上面提到的一个尊重。您需要在head标签中包含元标签代码：

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta charset="utf-8" />
<!--This is what you should include-->
<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">
<!---->

<meta name="viewport" content="width=device-width" />
<link href="/Content/site.css" rel="stylesheet" />

<link href="~/Content/booostrap/bootstrap-theme.css" rel="stylesheet" />
<link href="~/Content/booostrap/bootstrap-theme.min.css" rel="stylesheet" />

这对我很有效。但是IE和WIN10由于xls扩展名的原因，在下载时有一些冲突。然而，特殊字符的问题得到了纠正

在谷歌搜索后，我发现了一个解决方案编辑文件/tableExport/tableExport.js行280

var base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) } // New base64
// var base64data = "base64," + $.base64.encode(excelFile); OLD LINE
var base64data = "base64," + base64(excelFile); // New line with new base64

这都是

在var uri中使用以下代码：

var uri = 'data:application/vnd.ms-excel;charset=UTF-8;base64,'

输出
