# ExtendScript demos The main file is `test.jsx`. Target-specific files prepend target directives. Copy the `test.jsx` file as well as the `shim.js` and `xlsx.core.min.js` files to wherever you want the scripts to reside. The demo shows opening a file and converting to an array of arrays. NOTE: [We forked the minifier](https://www.npmjs.com/package/@sheetjs/uglify-js) and included a bugfix for ExtendScript's misparsing of switch statements.
