Create and convert large amounts of character data for free

Doing a lot of simple tasks over and over again can be frustrating. Excel macros and programming would make it easier, but I don't have the time and skills to create one. We have released a service that can be used conveniently at such times. All of them are services created and used when the administrator of this site was in trouble. Please use it when you need to process a large amount of data such as data editing or writing in Excel. All services are free.

Web analytics

It is a service that inputs the URL and automatically extracts information from the target WEB page. Just like a little scraping.

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.
