Looker studio is a great free product, offers many functions that is enough for a medium level reporting requirement

Looker studio provides a simple interface for creating dashboards and to visualize data. The cloud interface is easy to access and doesn't require software installation. There's an impressive amount of connectors to use, which makes data import easy. Looker only offers a limited amount of tools, which will probably feel very limiting to a user, who is accustomed to being able to do a lot with the data. However, the tools may be enough for someone who only needs to draw simple insights and doesn't want to use much time doing so. Especially for someone who is already using other Google products, this might be a good option.
