    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>home page</title>
<body style = "text-align:center;">
 <p id = "THIS_UP" style =
   "font-size: 15px; font-weight: bold;">
 <button onclick = "THIS_FUN()">
  click here
 <table id="table" align = "center" border="1px"></table>
  var el_up = document.getElementById("THIS_UP");
  var list = [
   {"col_1":"val_11", "col_2":"val_12", "col_3":"val_13"},
   {"col_1":"val_21", "col_2":"val_22", "col_3":"val_23"},
   {"col_1":"val_31", "col_2":"val_32", "col_3":"val_33"}
  el_up.innerHTML = "Click on the button to create the "
    + "table from the JSON data.<br><br>"
    + JSON.stringify(list[0]) + "<br>"
    + JSON.stringify(list[1]) + "<br>"
    + JSON.stringify(list[2]);
  function THIS_FUN() {
   var cols = [];
   for (var i = 0; i < list.length; i++) {
    for (var k in list[i]) {
     if (cols.indexOf(k) === -1) {
      // Push all keys to the array
   var table = document.createElement("table");
   // Create table row tr element of a table
   var tr = table.insertRow(-1);
   for (var i = 0; i < cols.length; i++) {
    var theader = document.createElement("th");
    theader.innerHTML = cols[i];
    // Append columnName to the table row
    for (var i = 0; i < list.length; i++) {
    // Create a new row
    trow = table.insertRow(-1);
    for (var j = 0; j < cols.length; j++) {
     var cell = trow.insertCell(-1);
     // Inserting the cell at particular place
     cell.innerHTML = list[i][cols[j]];
   var el = document.getElementById("table");
   el.innerHTML = "";
  1. First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
  2. Secondly, the <html> tag is used to indicate the beginning of an HTML document.
  3. As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
  4. Here, then we create a body tag. All the content which we want to show on browser’s screen or display is always written inside this codes.
  5. Here, as you can see that first we store json data into object. Here for this we put all the keys in a list.
  6. Then to show data in table, we create a table using table tag.
  7. Inside table we create tr to give headings to the table. Then we create our each th for tr as you can see above.
  8. Then for every entry in the object we create a cell and insert it into a particular row.
  9. And the columns is left empty if there is no value for this. We hope that you understand the above codes properly using these steps.
  10. At last, the <body> and <html> tags are closed with </body> and </html> respectively.

Conclusion :-

At last in conclusion, here we can say that with the help of this article we are able to understand how to populate html table with json data.
