Hi! We rely pretty heavily on the custom spreadsheets in the installed version. Our clients have very specific data requests that the custom spreadsheets make very easy to pull. Having that ability in version 7 would be a HUGE advantage. Please consider making them available!
Thanks for the feature request! Custom spreadsheets were a very useful tool in the installed app. Other options for getting information out of EnergyCAP 7 include using Report Designer, the Reports module, and Bill Lists.
