Historical Context of This Tool

The concept of converting characters to uppercase dates back to the earliest typewriters and teleprinters, where uppercase letters were easier to reproduce mechanically. With the development of the ASCII standard in the 1960s, computers gained a uniform way to represent text characters. Since then, case conversion utilities have been a fundamental part of programming, data processing, and digital communication systems.
