Date・Character analysis

What do you do when you have to regularly decompose and combine large amounts of data? It's often too much data to do manually. Can you use Excel function? Or can you make a macro? Both are time consuming and cumbersome. We have released a web service that can be used in such cases.


This is a free service about address data. We have a service that divide a large number of addresses into cities, streets, and addresses. Also a service that randomly generates addresses too.
