Aspose.Cells 支持将JSON（JavaScript对象表示法）文件转换为Excel工作簿。
将JSON转换为Excel工作簿
无需担心如何将JSON转换为Excel文件，因为Aspose.Cells for JavaScript通过C++提供了最佳解决方案。Aspose.Cells API支持将JSON格式转换为电子表格。可以使用JsonLoadOptions类设置导入JSON到工作簿的其他参数。
以下示例演示了将JSON导入Excel工作簿的代码。请查看代码以将source file转换为代码生成的xlsx文件。
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Aspose.Cells Example - Convert JSON to XLSX</h1>
<input type="file" id="fileInput" accept=".json" />
<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, Worksheet, Cell, 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 a JSON file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// create a Workbook object from uploaded file (JSON)
const wb = new Workbook(new Uint8Array(arrayBuffer));
// save file to xlsx format
const outputData = wb.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'sample_out.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Conversion completed successfully! Click the download link to get the XLSX file.</p>';
});
</script>

以下代码示例，使用 JsonLoadOptions 类指定额外设置，演示导入JSON到Excel工作簿。请参考代码将【源文件】(sample.json) 转换为Excel文件。

const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Create an options of loading the file.
const options = new JsonLoadOptions();
options.multipleWorksheets = true;
// Loads the workbook from JSON file
const book = new Workbook(new Uint8Array(arrayBuffer), options);
// Save file to xlsx format
const outputData = book.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);

downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully! Click the download link to get the converted file.</p>';

const blob = new Blob([outputData]);
