# Deno
2022-10-04 20:37:38 +00:00
[Deno](https://deno.land/) is a JavaScript runtime powered by V8.
:::caution Deno support is considered experimental.
Great open source software grows with user tests and reports. Any issues should
be reported to the Deno project for further diagnosis.

Each standalone release script is available at <https://cdn.sheetjs.com/>.
Using the URL imports, `deno run` will automatically download scripts and types:
<pre><code parentName="pre" {...{"className": "language-ts"}}>{`\
// @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';`}
</code></pre>
2022-06-05 22:43:44 +00:00
The `@deno-types` comment instructs Deno to use the type definitions.

:::warning
Older releases are technically available on [deno.land/x](https://deno.land/x/)
but the Deno registry is out of date.
[This is a known registry bug](https://github.com/denoland/dotland/issues/2072)
<https://cdn.sheetjs.com/> is the authoritative source for SheetJS scripts.

## Encoding support
2022-06-05 22:43:44 +00:00
2022-08-26 19:21:53 +00:00
If Encoding support is required, `cpexcel.full.mjs` must be manually imported:
2022-05-16 03:26:04 +00:00
<pre><code parentName="pre" {...{"className": "language-ts"}}>{`\
/* 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);`}
</code></pre>
