Case and accents
Classic ciphers often use the A-Z alphabet. Uppercase plus accent removal turns letters such as é, è, or ê into E.
Puzzle text cleaner
Prepare text before decoding by adjusting case, accents, spaces, and kept characters.
Codes
Clean puzzle text in real time: uppercase conversion, accent removal, letters-only or letters-and-digits filtering, space handling, and result grouping.

Additional information
What is the puzzle text cleaner for?
In a puzzle, the same message may include accents, spaces, punctuation, or line breaks that get in the way of some decoding methods. This cleaner does not solve the message: it prepares a more regular version that is easier to send to tools such as A1Z26, Caesar, Vigenère, Morse, or the code detector.
Kept characters
Raw text keeps everything. Letters + digits mainly removes punctuation. Letters only prepares a compact alphabetic string for substitutions, acrostics, frequencies, or shifts.
Spaces and groups
Removing spaces helps test continuous codes. Grouping by 2, 3, 4, or 5 characters then makes the result easier to read, like in some coded messages.
Preparation examples
| Goal | Useful settings | Example output |
|---|---|---|
| Test an alphabetic code | UPPER, accents removed, letters only | WHEREISTHEKEY |
| Keep numbers from a clue | UPPER, letters + digits | PUZZLE42CLUE120726 |
| Prepare block reading | Spaces removed, groups of 5 | PUZZL ECLUE |
Try next
After cleaning, analyze letters with Letter frequency, detect a format with the Code detector, test several transformations with the Multi-tool decoder, or convert letters and numbers with A1Z26.
