With the availability of JS engines and the success of server-side platforms,
it is feasible to build command-line tools for various workflows.

This demo covers a number of strategies for building standalone processors. The
goal is to generate CSV output from an arbitrary spreadsheet file.

## NodeJS

There are a few popular tools for compiling NodeJS scripts to CLI programs.

The demo script presents a friendly command line interface including flags:

```bash
$ ./xlsx-cli -h
Usage: xlsx-cli [options] <file> [sheetname]

Options:
  -V, --version            output the version number
  -f, --file <file>        use specified workbook
  -s, --sheet <sheet>      print specified sheet (default first sheet)
...
```

This demo was tested in the following deployments:

**`pkg`**

| Architecture | Version | Node Target | Date       |
|:-------------|:--------|:------------|:-----------|
| `darwin-x64` | `5.8.1` | `18.5.0`    | 2023-05-08 |
| `win32-x64`  | `5.8.1` | `18.5.0`    | 2023-05-08 |
| `linux-x64`  | `5.8.1` | `18.5.0`    | 2023-05-08 |

**`nexe`**

| Architecture | Version      | Node Target | Date       |
|:-------------|:-------------|:------------|:-----------|
| `darwin-x64` | `4.0.0-rc.2` | `14.15.3`   | 2023-05-08 |

</details>

0) Download the test file <https://sheetjs.com/pres.numbers>:

```bash
curl -LO https://sheetjs.com/pres.numbers
```

1) Download [`xlsx-cli.js`](pathname:///cli/xlsx-cli.js)

```bash
curl -LO https://docs.sheetjs.com/cli/xlsx-cli.js
```

2) Install the dependencies:

<Tabs groupId="pm">
  <TabItem value="npm" label="npm">
<CodeBlock language="bash">{`\
npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`}
</CodeBlock>
  </TabItem>
  <TabItem value="pnpm" label="pnpm">
<CodeBlock language="bash">{`\
pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`}
</CodeBlock>
  </TabItem>
  <TabItem value="yarn" label="Yarn" default>
<CodeBlock language="bash">{`\
yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`}
</CodeBlock>
  </TabItem>
</Tabs>

3) Follow tooling steps:

<Tabs>
  <TabItem value="nexe" label="Nexe">

Run `nexe` and manually specify NodeJS version 14.15.3

```bash
npx nexe -t 14.15.3 xlsx-cli.js
```

This generates `xlsx-cli` or `xlsx-cli.exe` depending on platform.

  </TabItem>
  <TabItem value="pkg" label="pkg">

Run `pkg`:

```bash
npx pkg xlsx-cli.js
```

This generates `xlsx-cli-linux`, `xlsx-cli-macos`, and `xlsx-cli-win.exe` .

  </TabItem>
  <TabItem value="boxednode" label="boxednode">

Run `boxednode`:

```bash
npx boxednode@2.0.1 -s xlsx-cli.js -t xlsx-cli
```

  </TabItem>
</Tabs>

4) Run the generated program, passing `pres.numbers` as the argument.  For
example, on an Intel Mac, `nexe` generates `xlsx-cli` so the command is:

```bash
./xlsx-cli pres.numbers
```

## Deno

`deno compile` generates a standalone executable that includes the entire JS
runtime as well as user JS code.

When compiling, the `--allow-read` option must be specified to allow the script
to read files from the filesystem with `Deno.readFileSync`.

<https://docs.sheetjs.com/cli/sheet2csv.ts> can be compiled and run from Deno.

This demo was last tested in the following deployments:

| Architecture | Version  | Date       |
|:-------------|:---------|:-----------|
| `darwin-x64` | `1.33.2` | 2023-05-08 |
| `win32-x64`  | `1.33.2` | 2023-05-08 |
| `linux-x64`  | `1.33.2` | 2023-05-08 |

0) Download the test file <https://sheetjs.com/pres.numbers>:

```bash
curl -LO https://sheetjs.com/pres.numbers
```

1) Test the script with `deno run`:

```bash
deno run -r --allow-read https://docs.sheetjs.com/cli/sheet2csv.ts pres.numbers
```

If this worked, the program will print a CSV of the first worksheet.

2) Compile and run `sheet2csv`:

```bash
deno compile -r --allow-read https://docs.sheetjs.com/cli/sheet2csv.ts
./sheet2csv pres.numbers
```
