你试过这个吗？

const conversion_cloud = require("groupdocs-conversion-cloud");

const clientId = "XXXX-XXXX-XXXX-XXXX";
const clientSecret = "XXXXXXXXXXXXXXXX";

const convertApi = conversion_cloud.ConvertApi.fromKeys(clientId, clientSecret);

let settings = new conversion_cloud.ConvertSettings();
settings.filePath = "path/to/csv/file";
settings.format = "html";
settings.outputPath = "ConvertedFiles";

let result = await convertApi.convertDocument(new conversion_cloud.ConvertDocumentRequest(settings));
