html export to excel javascript

Hello readers, Today I want to share my experience with exporting HTML to Excel using JavaScript. It was a challenging task that I had to deal with while working on my previous project. To begin with, there are a few approaches to achieve this. One method is to convert the HTML table into a CSV file and then open it in Excel. Another way is to use the data URI scheme to create an Excel file directly from HTML. The first method is straightforward, but it requires manual intervention from the user to open the CSV file in Excel. The second method is more seamless as it creates an Excel file directly from the HTML, but it has limited browser support. For my project, I opted for the second method and used the SheetJS library to generate an Excel file. Here's how I did it: First, I created a div element in HTML that contained the table I wanted to export. Then, I used JavaScript to convert the table into a JSON object using the jQuery plugin called tableToJSON. Next, I used SheetJS to create a workbook object and added a worksheet to it. I then looped through the JSON data and added it to the worksheet. Finally, I used the SheetJS function called writeXLSXFile to generate an Excel file and added a download link to it. The user could then download the file and open it in Excel. Here's some code snippets to help you understand better:

Exporting HTML to Excel using JavaScript#

Step 1: Convert HTML table to JSON using tableToJSON plugin#

    var table = $('#myTable').tableToJSON();

Step 2: Use SheetJS to create a workbook and add data to it#

    var workbook = XLSX.utils.book_new();
    var worksheet = XLSX.utils.json_to_sheet(table);
    XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");

Step 3: Generate Excel file and add download link to it#

    var wbout = XLSX.write(workbook, {bookType:'xlsx',  type: 'binary'});
    function s2ab(s) {
        var buf = new ArrayBuffer(s.length);
        var view = new Uint8Array(buf);
        for (var i=0; i
