Yesterday I asked Analytics Edge if they’d add a connector for Piwik, since some people might like to make more customized Piwik reports using Excel.
Apparently, they haven’t noticed much interest in such a feature, so it’s not coming anytime soon.
Unless there is a lot more interest in the future, it is not likely. I know Piwik interest has climbed over the past year due to the spam referral problems with GA, but I haven’t seen much interest in an Excel addin solution for it as yet. Most people seem happy with the api interface they provide.
If you’d like a Piwik plugin for Analytics Edge, let them know.
