FAQs
Answers to the most common questions about converting letters to numbers.
What is a letter-to-number converter?
It is a free browser tool that maps each letter of the alphabet to a numeric value — most commonly A=1 through Z=26 — so any word or sentence can be expressed as a series of numbers.
How does A1Z26 work?
A1Z26 assigns each letter its position in the alphabet: A is 1, B is 2, and so on through Z, which is 26.
Is the converter free?
Yes, completely free with no sign-up, subscription, or usage limit.
Does it support lowercase letters?
Yes. Uppercase and lowercase letters produce identical results.
Can I convert complete sentences?
Yes. You can paste single letters, words, full sentences, or entire paragraphs.
Are spaces preserved?
Yes. Spaces between words are kept in the output.
What is A0Z25?
A0Z25 is a zero-indexed variant where A=0 and Z=25.
What is reverse alphabet conversion?
Reverse alphabet mode flips the mapping so A=26 and Z=1.
What are ASCII letter values?
ASCII values are the numeric codes computers use to represent characters, such as 65 for uppercase A.
Is my entered text stored?
No. All conversion happens locally in your browser using JavaScript.
Can I use the tool on mobile?
Yes. The layout is fully responsive on phones, tablets, and desktops.
Can I copy the converted result?
Yes. Use the Copy Result button to copy the output to your clipboard instantly.
