Node.JS 中逐步將 XLS 轉換為 CSV

// Full working code for XLS to CSV conversion using Aspose.BarCode Cloud SDK

const { BarcodeApi, Configuration } = require('aspose-barcode-cloud');
const fs = require('fs');
const path = require('path');

// ==== Configuration ====
const config = new Configuration({
    clientId: "YOUR_CLIENT_ID",
    clientSecret: "YOUR_CLIENT_SECRET",
    // Optional: set a custom base URL if you use a private cloud
    // baseUrl: "https://api.aspose.cloud"
});

const apiInstance = new BarcodeApi(config);

// ==== Input / Output Paths ====
const inputFile = "sample.xls";               // Path to your local XLS file
const outputFolder = "output";                // Cloud folder for CSV files

// ---- 1. Upload XLS to cloud storage ----
async function uploadFile() {
    const fileData = fs.readFileSync(inputFile);
    await apiInstance.uploadFile({ path: inputFile, file: fileData });
    console.log(`Uploaded ${inputFile} to cloud storage.`);
}

// ---- 2. Convert XLS to CSV ----
async function convertXlsToCsv() {
    // Conversion options
    const options = {
        storage: "Default",               // Use default storage
        outPath: outputFolder,            // Destination folder
        format: "CSV",                    // Target format
        // Optional: delimiter, encoding, etc.
        delimiter: ",",
        encoding: "UTF-8"
    };

// Call the conversion endpoint (hypothetical method)
    const response = await apiInstance.convertDocument({
        name: inputFile,
        format: "csv",
        options: options
    });

console.log(`Conversion started. Check ${outputFolder} for CSV files.`);
    return response;
}

// ---- 3. Download generated CSV files ----
async function downloadCsvFiles() {
    const files = await apiInstance.getFilesList({ path: outputFolder });
    for (const file of files.value) {
        if (file.name.endsWith(".csv")) {
            const csvData = await apiInstance.downloadFile({ path: `${outputFolder}/${file.name}` });
            const localPath = path.join(__dirname, "result", file.name);
            fs.mkdirSync(path.dirname(localPath), { recursive: true });
            fs.writeFileSync(localPath, csvData.body);
            console.log(`Downloaded ${file.name} to ${localPath}`);
        }
    }
}

// ==== Execution Flow ====
(async () => {
    try {
        await uploadFile();
        await convertXlsToCsv();
        await downloadCsvFiles();
        console.log("XLS to CSV conversion completed successfully.");
    } catch (error) {
        console.error("Error during conversion:", error);
    }
})();
