Ternary Base 3 Character Substitution Translator Online

Convert lowercase English text into a slash-delimited three-digit base-3 letter code, or decode that code back into readable text. The full a–z, space and period table is stated openly, and any character outside it is reported instead of silently dropped. Try it online.

What is Ternary Base 3 Character Substitution Translator Online?

This agent encodes short English text into a custom three-digit base-3 letter code and decodes that code back. Each lowercase letter, a space and a period has one fixed code, and every code is followed by a slash. It is the same kind of letter-substitution scheme used by small novelty encoder pages, rebuilt as a conversation so you can see the table, ask for one direction, and get a clear report when a character cannot be represented.

It is not a numeral base converter. The codes look like ternary numbers, but they are assigned to letters in alphabetical order, so they do not express numeric values.

Key Features

Exact fixed table. a=001/ through z=222/, space=000/, period=000/000/, applied character by character.
Both directions. Send plain text to encode, or send slash-separated codes to decode.
Honest handling of unsupported characters. Capitals, digits and punctuation such as ? ; : are flagged in a report rather than quietly removed.
Table on demand. Ask for the full mapping at any time and it is printed in a copyable block.
Preservation check. Every conversion is verified so that decoding the emitted tokens reproduces the supported input characters.

How to Use

Type the text you want encoded, for example hello world, or paste a code string such as 022/012/110/110/120/000/212/120/200/110/011/.
Say which direction you want if it is not obvious, for example "encode this" or "decode this".
Read the result in the code block, then ask for a change such as lowercasing the input or removing the final slash for copying.

Example Use Cases

Encoding a short message for a puzzle. Turn meet me into 111/012/012/202/000/111/012/ for a treasure-hunt clue.
Decoding a pasted ternary code string. Paste 202/012/201/202/ and get test back, with any malformed token listed separately.
Checking a code before sharing it. Ask whether a string uses only valid three-digit tokens and whether the trailing slash is present.

Tips for Best Results

Write in lowercase and spell out numbers; digits have no code in this table.
Keep the trailing slash when you plan to decode later, and ask for a copy-ready version without it if you need one.
If a character is rejected, replace it with a supported alternative or ask for a list of what was skipped.
Remember that a period encodes to 000/000/, which decodes to two spaces rather than a period.

FAQ

What input does it accept? Lowercase letters a–z, the space character and the period. Codes must be three digits from 0 to 2 followed by a slash.

How accurate is the output? The mapping is fixed and deterministic, so results are exact for supported characters. Anything outside the table is reported, not guessed.

What makes this agent easy to check? It prints the whole table on request, lists exactly which characters could not be encoded along with their positions, and lets you request either direction in plain language.

Does it convert numbers to base 3? No. It is a letter-substitution code, not a numeric base converter.
