Convert Excel to HTML with tooltip using JavaScript via C++

There might be cases where the text is cut off in the generated HTML and you want to display the complete text as a tooltip on the hover event. Aspose.Cells for JavaScript via C++ supports this by providing HtmlSaveOptions.addTooltipText property. Setting the HtmlSaveOptions.addTooltipText property to true will add the complete text as a tooltip in the generated HTML.

The following image shows the tooltip in the generated HTML file.

The following code sample loads the source excel file and generates the output HTML file with the tooltip.

Sample Code

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Add Tooltip to HTML Example</title>
    </head>
    <body>
        <h1>Add Tooltip to HTML 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, SaveFormat, HtmlSaveOptions } = AsposeCells;
        
        AsposeCells.onReady({
            license: "/lic/aspose.cells.enc",
            fontPath: "/fonts/",
            fontList: [
                "arial.ttf",
                "NotoSansSC-Regular.ttf"
            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            if (!fileInput.files.length) {
                document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Instantiate a Workbook from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Create HtmlSaveOptions and enable tooltip text
            const options = new HtmlSaveOptions();
            options.addTooltipText = true;

            // Save workbook as HTML with the specified options
            const outputData = workbook.save(SaveFormat.Html, options);
            const blob = new Blob([outputData], { type: 'text/html' });
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'AddTooltipToHtmlSample_out.html';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download HTML File';

            document.getElementById('result').innerHTML = '<p style="color: green;">HTML file created successfully! Click the download link to get the result.</p>';
        });
    </script>
</html>
