将表单回复导出为 csv Google Apps 脚本

Question

有没有一种快速的方法可以以编程方式将 Google 表单中的所有响应导出到 csv？通过脚本调用 "Export responses to csv" 之类的东西。

现在我正在以摇滚艺术的方式来做：

遍历我要导出的表单 (~75)
- 打开每张表格var form = FormApp.openById(formId);
- 获得回复：var formReponses = form.getResponses();（每个表单有 0 到 700 个回复）
- 迭代响应并获取项目响应：var preguntes = formReponses[r].getItemResponses();
  - 对于每个项目响应，将其转换为 csv/json
- 将响应导出到驱动器文件

这 非常慢 而且它 一遍又一遍地挂起 ，所以我不得不以 50 个响应为一组导出响应并保存它们在驱动器分隔文件中。在下次执行时（让服务器冷却一段时间后），我再次执行脚本，跳过在块文件中找到的响应数。

此外，我不确定 Google 在执行 form.getResponses(); 时是否保持响应顺序（实际上我发现如果表格已被修改，顺序就不一样了）

有更好的方法吗？

在@JackBrown 的帮助下，我设法编写了一个 Chrome 扩展来下载回复（可能很快会在 github 中）。这将等待 formIds 对象中的每个下载完成，然后提示下一个：

'use strict';

function startDownload() {
    const formIds = {
        'Downloads-subfolder-here': {
            'Download-filename-here': '1-cx-aSAMrTK0IHsQkE... {form-id here}',
            'Another-filename-here': '...-dnqdpnEso {form-id here}',
            // ...
        },
        'Another-subfolder-here': {
            'Download-filename-here': '1-cx-aSAMrTK0IHsQkE... {form-id here}',
            'Another-filename-here': '...-dnqdpnEso {form-id here}',
            // ...
        },
    };

    const destFolders = Object.keys(formIds);
    const downloads = [];

    for (let t = 0, tl = destFolders.length; t < tl; t += 1) {
        const destFolder = destFolders[t];
        const forms = Object.keys(formIds[destFolder]);

        for (let f = 0, fl = forms.length; f < fl; f += 1) {
            const formName = forms[f];
            downloads.push({
                destFolder,
                formName,
                url: `https://docs.google.com/forms/d/${formIds[destFolder][formName]}/downloadresponses?tz_offset=-18000000`,
                filename: `myfolder/${destFolder}/${formName.replace(/\//g, '_')}.csv`,
            });
        }
    }

    const event = new Event('finishedDownload');
    const eventInterrupt = new Event('interruptedDownload');
    let currId;

    chrome.downloads.onChanged.addListener((downloadDelta) => {
        if (downloadDelta.id === currId) {
            if (downloadDelta.state && downloadDelta.state.current === 'complete') {
                document.dispatchEvent(event);
            } else if (downloadDelta.state && downloadDelta.state.current === 'interrupted') {
                console.log(downloadDelta);
                document.dispatchEvent(eventInterrupt);
            }
        }
    });

    downloads.reduce((promise, actual) => {
        return promise.then((last) => (last ? new Promise((resolve) => {
            const { url, filename, destFolder, formName } = actual;
            function listener() {
                document.removeEventListener('finishedDownload', listener);
                document.removeEventListener('interruptedDownload', listener);
                resolve(true);
            };
            function interrupt() {
                document.removeEventListener('finishedDownload', listener);
                document.removeEventListener('interruptedDownload', listener);
                resolve(false);
            }
            console.log(`Processant ${destFolder}, ${formName}: ${url}`);
            document.addEventListener('finishedDownload', listener);
            document.addEventListener('interruptedDownload', interrupt);
            chrome.downloads.download({ url, filename }, (downloadId) => {
                currId = downloadId;
                if (!downloadId) {
                    console.log();
                    console.log('Error downloading...');
                    console.log(runtime.lastError);
                    resolve();
                }
            });
        }) : Promise.resolve(false)));
    }, Promise.resolve(true));
}

chrome.browserAction.onClicked.addListener((/*tab*/) => startDownload());
