我在随机时间创建了几个CSV文件，其中包含客户端地址（少于3000个）。我可以将它发送到谷歌地图引擎来生成地图视图吗？ （尝试自动化而不是丢弃文件）谢谢

您可以将Maps Engine API用于insert rows to an existing table或upload data files (CSV, KML, shape files) to a new table。
此处唯一的问题是API仅支持核心“Maps Engine”产品，而不是Lite或Pro产品。如果您想进行试验，可以使用直线Maps Engine产品的免费等级。

我的要求很简单，找到了解决问题的简单方法。刚刚在运行时生成一个HTML页面，所有文本地址都插入到JavaScript数组中，然后循环遍历它以生成地理编码和标记的地方。唯一的缺点是性能，因为Google要求连续的地理编码请求，间隔为1秒。 我使用VBA代码生成HTML
