What this calculator does
This tool converts a lowercase word into its uppercase (all capital letters) form, letter by letter.
How the calculation works
Select each lowercase letter of the word you want to convert, one dropdown per letter position (leave unused positions blank). The calculator joins your selected letters into the original lowercase word, then converts every letter to its capital form to display the uppercase version alongside it.
This tool is intended for general writing, formatting, and educational use.
