使用JavaScript通过C++进行JSON

将Excel工作簿转换为JSON

Aspose.Cells API 提供了将电子表格转换为 JSON 格式的支持。要导出工作簿到 JSON,请将 SaveFormat.Json 作为 Workbook.save(string, SaveFormat) 方法的第二个参数传递。你还可以使用 JsonSaveOptions 类来指定导出工作表到 JSON 的其他设置。

以下代码示例演示如何使用 SaveFormat.Json 枚举成员将活动工作表导出为 JSON。请参阅代码,将 source file 转换为 输出 JSON 文件。以作参考。

<!DOCTYPE html>
<html>
    <head>
        <title>Aspose.Cells Example - Convert Workbook to JSON</title>
    </head>
    <body>
        <h1>Convert Workbook to JSON Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Convert to JSON</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, Utils } = 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 Workbook from uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Save workbook as JSON
            const outputData = workbook.save(SaveFormat.Json);
            const blob = new Blob([outputData], { type: 'application/json' });
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'book1.json';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download JSON File';

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