Deno

Each standalone release script is available at https://cdn.sheetjs.com/.

Using the URL imports, deno run will automatically download scripts and types:

{`\
// @deno-types="https://cdn.sheetjs.com/xlsx-${current}/package/types/index.d.ts"
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs';`}

XLS Codepage support (click to show)

If XLS support is required, cpexcel.full.js must be manually imported:

{`\
/* load the codepage support library for extended support with older formats  */
import * as cptable from 'https://cdn.sheetjs.com/xlsx-${current}/package/dist/cpexcel.full.mjs';
XLSX.set_cptable(cptable);`}
