Export Excel to HTML with GridLines via JavaScript

Export Excel to HTML with GridLines

The following sample code creates a workbook, fills its worksheet with some values, and then saves it in HTML format after setting the HtmlSaveOptions.exportGridLines() to true.

<!DOCTYPE html>
<html>
    <head>
        <title>Export To HTML With GridLines Example</title>
    </head>
    <body>
        <h1>Export To HTML With GridLines Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

    <script src="aspose.cells.js.min.js"></script>
    <script type="text/javascript">
        const { Workbook, HtmlSaveOptions, SaveFormat } = AsposeCells;
        
        AsposeCells.onReady({

            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {

            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download HTML File';
