Text Processing
Convert between letters and numbers (A=1, B=2, … Z=26) with configurable separator and case, decode numbers back to letters, and compute the letter sum of any text.
Details
A1Z26 is the simplest substitution cipher: each Latin letter maps to its position in the alphabet (A=1, B=2, …, Z=26). This workbench encodes text to numbers, decodes a sequence of numbers back into letters, and computes a letter-sum (useful for numerology / gematria-style puzzles). You control the output separator (hyphen, space, comma, none) and the case handling (force upper/lower or preserve). Non-letter characters are ignored on encode and reported; on decode, invalid tokens (outside 1–26) are skipped and counted.
Execution
Fill in the form, run the tool, and review the result in one place.

Tool usage guide
A1Z26 Letter-Number Workbench converts Latin letters to alphabet positions using A=1 through Z=26, decodes number sequences back to letters, and calculates letter sums. Choose the conversion mode, output separator, and letter case.
Background
A puzzle creator wants to publish a short numeric clue based on the first three letters of the alphabet.
Problem
The clue needs a clear A1Z26 representation with separators between each value.
How to use
Enter "ABC", choose Encode mode, select the hyphen separator, and use uppercase case handling.
Text: ABC; Mode: Encode; Separator: Hyphen (-); Case: Uppercase (ABC)Outcome
The tool produces "1-2-3".
Background
A puzzle includes the sequence 20-8-5 and uses the A1Z26 mapping.
Problem
The solver needs to turn the number sequence into readable letters.
How to use
Enter "20-8-5", choose Decode mode, keep the hyphen separator, and select uppercase output.
Text: 20-8-5; Mode: Decode; Separator: Hyphen (-); Case: Uppercase (ABC)A1Z26 maps each Latin letter to its alphabet position: A=1, B=2, through Z=26.
Yes. Use Encode mode to convert letters into A1Z26 numbers.
Yes. Use Decode mode with a sequence of numbers from 1 through 26.
Non-letter characters are ignored and reported in the output.
Number tokens outside the range 1–26 are skipped and counted.
Outcome
The tool decodes the sequence as "THE".
Background
A word-game enthusiast wants the total A1Z26 value of a text string.
Problem
Adding the alphabet positions manually can be slow and error-prone.
How to use
Enter the text, choose Letter sum mode, and run the tool.
Mode: Letter sum (A=1…Z=26, total)Outcome
The tool returns the total of the A1Z26 values for the letters in the text.
