Hi, this time I have come up with a jquery basics tutorial which discusses about how to convert json to html table. In simple terms we are going to use jquery to display data from a json file in neat table format with added pagination and search options to it. To make our life easier there is an excellent jquery plug-in called ‘DataTables’ which we will use for this task. DataTables is a flexible jquery tool which adds up advanced interaction controls to any HTML table. Using this we can easily add pagination, instant search or multi-column ordering to the html table. Moreover it supports all modern day data sources like DOM, JavaScript, Ajax and server-side processing.
Convert JSON Data to HTML Table using jQuery
As an example let’s take the below sample json file which contains an array of objects and display it in html table using datatables.

Now let's see about converting this json data to html table.
Step 1: First you need the datatables plug-in in place to start working. So download datatables plug-in here and extract its contents and move ‘media’ directory to your working folder.
Step 2: Having the required datatables files in place, now we have to link them to the html file. Create a file ‘index.html’ and link the datatables ‘css’ and ‘js’ files like this.
<html>
<head>
<!-- link datatables css -->
<link rel="stylesheet" type="text/css" href="/path/to/jquery.dataTables.css">
</head>
<body>
...
<!-- load jquery -->
<script type="text/javascript" src="/path/to/jquery-1.10.2.js"></script>
<!-- load datatables js library -->
<script type="text/javascript" src="/path/to/jquery.dataTables.js"></script>
</body>
</html>
Remember to include the jquery library before datatables ‘js’ file as the plug in is built over jquery.
Step 3: Now it's time to create a html table structure which we will map to our json data source later. We should determine what are the columns we want to appear on the table and create the table's header and footer with appropriate column names.
<table id="empTable" class="display" width="100%" cellspacing="0">
<thead>
<tr>
<th>Name</th>
<th>Designation</th>
<th>Office</th>
<th>Extension</th>
<th>Joining Date</th>
<th>Salary</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Name</th>
<th>Designation</th>
<th>Office</th>
<th>Extension</th>
<th>Joining Date</th>
<th>Salary</th>
</tr>
</tfoot>
</table>
Using the css class ‘.display’ will create the table with alternative striped rows (zebra cross style).
Step 4: Finally we should populate the html table with the data from json source by mapping to the right table columns.
<script type="text/javascript">
$( document ).ready(function() {
$('#empTable').dataTable({
"ajax": "empdata.json",
"columns": [
{"data": "name"},
{"data": "designation"},
{"data": "office"},
{"data": "extension"},
{"data": "joining_date"},
{"data": "salary"}
]
});
});
</script>
- The dataTable() method will initialize the datatables. Its behavior can be controlled by passing parameters for various options and we have used two options in the above code. (I planned to keep the code as simple as possible and used only the basic options required but you can try out more).
- The ajax option will load the data from the given ajax source. Here in our case it’s the path to the json file.
- The columns option will map the table columns to the data source keys.
Now run the index.html file and you can see a nicely designed html table with added enhancements like instant-search at the top and pagination links at the bottom. You can also sort the table columns like you prefer.

});
});
