I am not able to find it; Google announced that they would have an exporter for the data that's presently locked-into Wave. Has there been any news about it?
Click the box with three dots at the top right of a wave and then choose export.
So I have to manually click every single wave that I've created and do it. :-/ Is there an exporter that's available?
EDIT: it looks like it allows one to export waves in batches of 10.
