How to Use Letter to Number Converter
- Paste a word, phrase, sentence, or mixed text into the input box.
- Choose the separator that matches the target format: spaces for readability, commas for spreadsheets, hyphens for puzzle notation, or new lines for one value per row.
- Turn preservation on when you want punctuation, spaces, or existing digits to remain visible in the output; turn it off when you need only the numeric letter positions.
- Copy the generated sequence and verify any non-English letters manually, because the converter only maps A through Z.
Formula & Theory - Letter to Number Converter
A/a = 1
B/b = 2
...
Z/z = 26Each English letter is normalized case-insensitively before conversion. A and a share the same value, so capitalization does not change the result.
Characters outside the English alphabet do not have alphabet positions in this scheme. The preserve option decides whether those characters stay in the output or are skipped.
This is an ordinal alphabet mapping, not encryption by itself. It can support simple ciphers or puzzles, but it does not provide security.
