Address Copy Helper is a free Chrome add-on developed by awtnb.cws that aims to simplify the process of copying Japanese addresses. With this handy tool, users can easily copy Japanese addresses as postal codes separated by tabs.

One of the key features of Address Copy Helper is its ability to convert full-width numbers and alphabets to half-width, making it easier to work with the copied address. Additionally, the add-on automatically trims the first postal code symbol (U+3012) and converts horizontal bars between numbers to U+002D (-).

It is important to note that Address Copy Helper only works on HTTPS sites, ensuring a secure browsing experience. Whether you're working with real or fictional addresses, this add-on will save you time and effort when copying Japanese addresses.
