|
|
[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>
|
|
|
|
|
|

|
|
|
The `@deno-types` comment instructs Deno to use the type definitions.

|
Older releases are technically available on [deno.land/x](https://deno.land/x/)
|
|
|
|
|
but the Deno registry is out of date.

## 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>
