Google apps script 将大的google sheets文件导出为批量大小为500的多个csv
我想从Google Sheets下载一个10000行长的单数表单，将其拆分为20个单独的csv文件，每个文件的批量大小为500行。是否可以使用Google Sheets完成此操作？我找不到对Sheets的本机支持，无法下载并将文件分成多个部分/片段。但是我找到了一个Google apps script 将大的google sheets文件导出为批量大小为500的多个csv,google-apps-script,google-sheets,Google Apps Script,Google Sheets,我想从Google Sheets下载一个10000行长的单数表单，将其拆分为20个单独的csv文件，每个文件的批量大小为500行。是否可以使用Google Sheets完成此操作？我找不到对Sheets的本机支持，无法下载并将文件分成多个部分/片段。但是我找到了一个googleapps脚本代码，可以将工作表保存到csv中 所以我所做的就是修改代码，然后让它将一张工作表转换成多个csv 问题是，它会将所有这些文件上传到登录的谷歌硬盘中的一个文件夹中，然后你可以将它们下载到一个zip文件中。（我将在
