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.

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:

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

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

1. Test the script with deno run:

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:

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

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:

$ ./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)
...

1. Download xlsx-cli.js

2. Install the dependencies:

{`\ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`} {`\ pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`} {`\ yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz exit-on-epipe commander@2`}

3. Follow tooling steps:

Run nexe and manually specify NodeJS version 14.15.3

npx nexe -t 14.15.3 xlsx-cli.js

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

Run pkg:

npx pkg xlsx-cli.js

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