Random Letter Generator
A–Z letters, solo or in sequences
Each letter is produced from a single draw between 0 and 25 offset from the ASCII code for lowercase a, then uppercased or left alone according to the Case dropdown. Uppercase gives you A through Z, Lowercase gives you a through z, and Mixed flips per letter rather than per batch, so a run of twenty is a genuine mixture. The Separate with spaces checkbox changes the join — off, you get one unbroken twenty-character string, which is the form most captcha-style and code challenges want; on, you get A T K P Q separated by single spaces, which is the form a worksheet or a word game wants. Count is the number of letters, from 1 to 100, and the whole run comes back as a single line.
Draw random letters from A to Z, individually or in groups, with uppercase, lowercase or mixed case options. Popular for word games, teaching the alphabet and lottery-style draws.
