</div>

datalist = {{1, 2}, {2, 4}, {3, 8}, {4, 16}};

Button[“Save”,  
Export[SystemDialogInput[“FileSave”], datalist, “Table”]]

After I run it, I can see the filename but cannot find it as a file. Thanks.

It seems that without `Method->"Queued"` `Export` will not wait for your choice. Use it then:

```
Button["Save", 
 Export[SystemDialogInput["FileSave"], datalist, "Table"], 
 Method -> "Queued"]

```
