Write a web app to upload a file, read the content then return the content in HTML table using JSON format then display the result dynamically at current HTML page. Below is the JSON return by a PHP script.
{filename: 'input.dat',total_recipient: '1',totalcolumn: '3',samples: '<table width="400px"><thead><tr><th>Column 1</th><th>Column 2</th><th>Column 3</th></tr></thead><tbody><tr><td>name</td><td>phone no</td><td>address</td></tr></tbody></table>',columntag: '{Col_1},{Col_2},{Col_3},'}
