import ExcelViewer from "excel-viewer";

new ExcelViewer("#excel-view", "http://example.com/test.xls", {
    theme: "dark",
    lang: "zh_cn"
});

Authorization

If your excel file needs authorization, you can help you through this.

iframe

<iframe id="excel-viewer"></iframe>

<script>
let iframe = document.getElementById("excel-viewer");
// example with axios
axios({
    url: "http://example.com/test.xls",
    method: "GET",
    headers: { "Authorization": "Your Authorization Token" }, // authorization token
    responseType: "blob"
}).then(blob => {
    let localUrl = URL.createObjectURL(blob) + ".xls"; // add excel file suffix
    iframe.src = "https://unpkg.com/excel-viewer@1.0.0/dist/index.html?file=" + localUrl;
})
</script>

CDN

<div id="excel-view"></div>

<script>
// example with axios
axios({
    url: "http://example.com/test.xls",
    method: "GET",
    headers: { "Authorization": "Your Authorization Token" }, // authorization token
    responseType: "arraybuffer"
}).then(res => {
    new ExcelViewer("#excel-view", res.data);
})
</script>

ESM

<template>
	<div ref="excel-view"></div>
</template>
<script>
import axios from "axios";
import ExcelViewer from "excel-viewer";

// example with vuejs and axios
export default {
    mounted() {
        let container = this.$refs["excel-view"];
  
        axios({
            url: "http://example.com/test.xls",
            method: "GET",
            headers: { "Authorization": "Your Authorization Token" }, // authorization token
            responseType: "arraybuffer"
        }).then(res => {
            new ExcelViewer(container, res.data);
        })
    }
}
</script>

!!Known Restrictions

If you need to use multiple excel-viewer on one page, the ESM method will not be able to set different theme modes for the previewer and cannot use the theme switching function. You can use the iframe embedded approach to solve this problem perfectly.

<div id="excel-view1"></excel-view>
<div id="excel-view2"></excel-view>
<script>
    // right
    new ExcelViewer("#excel-view1", "http://example.com/test.xlsx", { theme: "dark", themeBtn: false });
    new ExcelViewer("#excel-view2", "http://example.com/test.xlsx", { theme: "dark", themeBtn: false });
    // error
    new ExcelViewer("#excel-view1", "http://example.com/test.xlsx", { theme: "dark", themeBtn: true }); // error，themeBtn should disabled
    new ExcelViewer("#excel-view2", "http://example.com/test.xlsx", { theme: "light", themeBtn: false }); // error, multiple viewer theme mode must be the same
</script>
