Conversion de Classeur Excel en HTML

L’API Aspose.Cells offre un support pour l’exportation de feuilles de calcul au format HTML. À cette fin, Aspose.Cells utilise la classe HtmlSaveOptions pour offrir la flexibilité de contrôler plusieurs aspects du HTML de sortie.

L’exemple de code ci-dessous montre comment enregistrer un classeur en tant que fichier HTML en utilisant JavaScript via C++ :

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example</title>
    </head>
    <body>
        <h1>Aspose.Cells - Convert Excel to HTML</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Convert to HTML</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 } = 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();

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

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

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

Conversion de Classeur Excel en Fichiers MHTML

MHTML combine le HTML normal avec des ressources externes (c’est-à-dire le contenu généralement lié, comme les images, animations, audio, etc.) en un seul fichier. Il est utilisé pour les courriels avec l’extension de fichier .mht. Aspose.Cells prend en charge la lecture et l’écriture des fichiers MHTML.

L’exemple de code ci-dessous montre comment enregistrer un classeur en tant que fichier MHTML en utilisant JavaScript via C++ :

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example - Save as MHT</title>
    </head>
    <body>
        <h1>Save Excel as MHT 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 } = 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');
            const resultDiv = document.getElementById('result');
            if (!fileInput.files.length) {
                resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

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

            // Load your source workbook from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Save file to MHT format
            const outputData = workbook.save(SaveFormat.MHtml);
            const blob = new Blob([outputData], { type: 'application/octet-stream' });
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'out.mht';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download MHT File';

            resultDiv.innerHTML = '<p style="color: green;">File converted to MHT successfully! Click the download link to get the result.</p>';
        });
    </script>
</html>
