Step-by-Step Guide: Display Excel Data in HTML Table using JavaScript
Here are step-by-step guid to display Excel data in an HTML table using JavaScript by following these steps:
- Step 1: Create an HTML file and include a script tag to reference your JavaScript file.
- Step 2: Use the XMLHttpRequest object to read the Excel data from a CSV or JSON file.
- Step 3: Parse the Excel data into a JavaScript array using a CSV or JSON parser.
- Step 4: Create an HTML table using the createElement() method and set its id attribute to a unique identifier.
- Step 5: Use a loop to iterate through the data array and add a new row to the HTML table for each record.
- Step 6: Add a new column to each row for each field in the Excel data.
- Step 7: Set the text content of each cell in the table to the corresponding value from the Excel data.
- Step 8: Append the HTML table to a container element in the HTML file, such as a “div” element.
Here’s an example code snippet that demonstrates how to display Excel data in an HTML table using JavaScript:

<!DOCTYPE html> <html> <head> <title>Excel to HTML Table</title> </head> <body> <div id="container"></div> <script> // Step 1: Define the Excel file path const excelFilePath = "data.csv"; // Step 2: Read the Excel data using XMLHttpRequest const xhr = new XMLHttpRequest(); xhr.open("GET", excelFilePath, true); xhr.onload = function() { if (this.status === 200) { // Step 3: Parse the Excel data into a JavaScript array const excelData = JSON.parse(this.responseText); // Step 4: Create the HTML table const table = document.createElement("table"); table.id = "excelTable"; // Step 5: Add rows and columns to the HTML table for (let i = 0; i < excelData.length; i++) { const row = table.insertRow(); for (let j = 0; j < excelData[i].length; j++) { const cell = row.insertCell(); cell.textContent = excelData[i][j]; } } // Step 8: Append the HTML table to the container element const container = document.getElementById("container"); container.appendChild(table); } }; xhr.send(); </script> </body> </html> |
In this example the excel data is assumed to be in a CSV file named data.csv. This code uses XMLHttpRequest to read the data from the file, and JSON.parse() to convert the CSV data into a JavaScript array.
Then creates an HTML table using document.createElement() and adds rows and columns to the table using a loop. Finally, the HTML table is appended to the container element using appendChild().
