Node.JSでのXLSからCSVへのステップバイステップ変換

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

// ==== Configuration ====
const config = new Configuration({

    // baseUrl: "https://api.aspose.cloud"
});

// ==== 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.`);

        // Optional: delimiter, encoding, etc.

// Call the conversion endpoint (hypothetical method)

        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 });

            console.log(`Downloaded ${file.name} to ${localPath}`);
        }

}

// ==== Execution Flow ====
