Quick explanation
Accents are reduced to their base letters, then only A-Z letters are counted. Both A=0 and A=1 sums stay visible at the same time, so you do not have to choose a convention too early.

Additional information
Understanding letter sums
A letter sum replaces each letter with its alphabet value, then adds the values together. In puzzles, two conventions often appear: A=0 and A=1. This tool shows both at the same time so you can compare results quickly.
A=0
A is 0, B is 1, C is 2, up to Z as 25. This convention is common when the calculation relates to shifts or computer-style indexing.
A=1
A is 1, B is 2, C is 3, up to Z as 26. This is the most intuitive convention when talking about alphabet rank.
Accents and signs
É, È, or Ê become E, À becomes A, and Ç becomes C. Spaces, digits, and punctuation are not added, so only A-Z letters are counted.
Simple example
| Word | Letters | A=0 sum | A=1 sum |
|---|---|---|---|
| APP | A + P + P | 0 + 15 + 15 = 30 | 1 + 16 + 16 = 33 |
| KEY | K + E + Y | 10 + 4 + 24 = 38 | 11 + 5 + 25 = 41 |
When to use this tool
Letter sums are useful for checking a keyword, comparing clues, spotting a hidden value, or testing a numerical path in a treasure hunt. To prepare text, use the Puzzle text cleaner. To convert letter by letter, use A1Z26. To analyze positions or frequencies, also see Letter positions and Letter frequency.
