        <a id="downloadLink" style="display: none;">Download Result</a>
        <div id="result"></div>
    </body>

    <script src="aspose.cells.js.min.js"></script>

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

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

            // Instantiate a new Workbook (if a file is provided, open it; otherwise create a new workbook)
            let workbook;
            if (fileInput.files.length) {
                const file = fileInput.files[0];
                const arrayBuffer = await file.arrayBuffer();
                workbook = new Workbook(new Uint8Array(arrayBuffer));
            } else {
                workbook = new Workbook();
            }

            // Get the first worksheet
            const worksheet = workbook.worksheets.get(0);

            // Add some text in cell A1
            worksheet.cells.get("A1").putValue("Here");

            // Add a comment to A1 cell
            const commentIndex = worksheet.comments.add("A1");
            const comment = worksheet.comments.get(commentIndex);

            // Set its vertical alignment setting            
            comment.commentShape.textVerticalAlignment = TextAlignmentType.Center;

            // Set the Comment note
            comment.note = "This is my Comment Text. This is Test.";

            const shape = worksheet.comments.get("A1").commentShape;

            shape.fill.solidFill.color = Color.Black;
            const font = shape.font;

            styleFlag.fontColor = true;
            shape.textBody.format(0, shape.text.length, font, styleFlag);

            // Save the Excel file
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);

            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Modified Excel File';
