How To Export Html Table To Excel Using Javascript

Hi there, how is your day Programmer? Have you ever tried to export your HTML table to an Excel sheet? If you tried and failed to manage that, here I am to solve your problem.

Before we get started, make sure that you have a bit of knowledge about HTML, CSS, and javascript. It is not necessary to be an expert on them. But it will be easier for you to understand this tutorial if you are already familiar with them.

HTML is awesome. It helps you to build the main structure of a website. It’s the main part of a website. Basically, everything we see in a website from the front-end is built with HTML. You can even create amazing pieces of stuff like form, tables, lists, and much more using just HTML.

Excel

The first thing that we need to create that function is an HTML file. An HTML file will contain all our HTML tables, JavaScript code, and a little CSS code. We will mix everything in that one file to export our HTML table to Excel. So, without further talking, let’s get started.

HTML Code

First of all, create a file named index.html or you can rename it as like as you want. Now, open that file using a text editor like sublime text, visual studio code, or any of your favorite text editors. After opening that file using text editor, add the following code to it.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>HTML Table To Excel</title>
</head>
<body>
  <div class="blogdesire-wrapper">
    <table id="testTable">
    <thead>
      <tr>
        <th>No.</th>
        <th>Person Name</th>
        <th>Person Age</th>
        <th>Person Hobby</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>01</td>
        <td>John Doe</td>
        <td>18</td>
        <td>Programming</td>
      </tr>
      <tr>
        <td>02</td>
        <td>Jonas Smith</td>
        <td>22</td>
        <td>Fishing</td>
      </tr>
      <tr>
        <td>03</td>
        <td>Ada Jonson</td>
        <td>19</td>
        <td>Travelling</td>
      </tr>
    </tbody>
  </table>
    <button onclick="tableToExcel('testTable', 'W3C Example Table')">Export</button>
  </div>
</body>
</html>

Save the file, and open it with a web browser. You will find a table with some data like name, age, hobby, etc.

CSS Code

To make it a bit nicer, add the following code at the beginning of the body tag.

<style>
.blogdesire-wrapper{
  margin: 20px auto;
  padding: 20px;
  box-shadow: 0 0 15px 0 rgba(0,0,0,.3);
  text-align: center;
  width:100vw;
  max-width:400px;
}
td,th{
  border-bottom: 1px solid rgba(0,0,0,.3);
  padding:15px;
}
button{
  border: none;
  padding: 10px 20px;
  border-radius:4px;
  color:white;
  background: orangered;
  margin-top:20px;
}
</style>

This will add some style to your HTML table.

JavaScript Code

Now, it’s time to add the javascript code to export our HTML table to Excel. Copy the following code below and paste it between the header tags of your HTML file.

<script type="text/javascript">
var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    window.location.href = uri + base64(format(template, ctx))
  }
})()
</script>

After doing everything correctly, you should have an HTML table and a button colled Export in your HTML file. If you hit on the Export button of your HTML file, your HTML table should be converted and downloaded as an Excel file.

Here is a little demo of that.

    Long time supporter, and thought I’d drop
    a comment.

    Your wordpress site is very sleek – hope you don’t mind me asking what theme you’re using?
    (and don’t mind if I steal it? :P)

    I just launched my site –also built in wordpress like
    yours– but the theme slows (!) the site down quite a bit.

    In case you have a minute, you can find it by searching
    for “royal cbd” on Google (would appreciate any feedback) – it’s
    still in the works.

    Keep up the good work– and hope you all take care of yourself during
    the coronavirus scare!

      Hi there, thanks for your support. I am using OceanWP as my wordpress site theme. You also can use it for your site. I wouldn’t mind cause I didn’t build this theme 😊

    Woah! I’m really digging the template/theme of this website.
    It’s simple, yet effective. A lot of times it’s challenging to get that “perfect balance”
    between superb usability and visual appearance. I must say that you’ve done a superb job with this.
    Also, the blog loads super fast for me on Chrome. Excellent Blog!

    1. MD Khokon Mia April 4, 2020

      Thank you. In case you are trying to use the same theme you are welcome the use the OceanWP theme. 😊

    Keep on posting!

    Pretty! This was an extremely wonderful post. Thanks for providing this info.

    The exposed solution is efficient and elegant.
    Using Chrome, Firefox and Opera the table is correctly exported in Excel.
    When I use IE11 (on windows 8) appears this message: “No apps are installed to open this type of link (data)”.
    Is there a solution for IE11?

    Thank you in advance.

    This works great but I am getting an error:”the file format and extension of don’t match”. Is there anyway to fix this or change the output file to xlsx instead of xls

    1. MD Khokon Mia February 10, 2020

      In this javascript code, we are just requesting for an excel file. The extension is provided by the browser.
