In Node.JS, something like this:

Code:

var AMX = require('amx').AMX;
var fs = require('fs');
var util = require('util');

var amx_data = new AMX(fs.readFileSync('filename.amx'));

console.log(util.inspect(amx_data, { showHidden: true, depth: null }));

You could do it in modern browsers also, as long as you know how to get a Buffer from a file upload.
