After reading Chris Ainsworth’s post on Multiple Business Locations, I started incorporating his JSON-LD markup examples on websites. Below is a tool for stringing structured data together for multiple businesses easier.

**NOTE, tool is temporarily busted. To use, you’ll have to remove all <p> and <br/> from the code.**
