There are two ways of getting your Google account info.

The first is the bulk download. While Google removed bulk uploads, they left the download links for accounts and campaigns.

The other method is the editor. One can export an entire account to an excel file from the AdWords editor.

As the outputs have changed slightly over time, you might have to move/remove some columns, but it should work without a lot of work.

I think Google have made this more challenging by disabling bulk downloads. There is a work around, but it’s not as cut and dried as Yahoo portray in their seminars.
