How to use Convert ATASCII to ASCII
- 1. Paste the ATASCII codes. Enter the Atari character codes in the input pane, separated by spaces, like 65 for the letter A. Sequences dumped from emulator memory or extracted from ATR images work directly.
- 2. Let the mapping run. No options are needed. Each code is translated through the ATASCII table into its ASCII counterpart, with the Atari EOL code 155 becoming a normal line break in the output.
- 3. Review the decoded text. Codes in the ranges where ATASCII and ASCII agree translate silently, while Atari-specific graphics and control codes are resolved to their nearest modern representation so nothing is dropped.
- 4. Copy the readable result. Copy the recovered text into a modern editor, an archive note or a transcription project. From here it behaves like any ordinary file.
When to use Convert ATASCII to ASCII
Convert ATASCII to ASCII decodes Atari 8-bit character codes back into modern text. Data pulled from Atari disk images, BASIC listings and memory dumps arrives as raw ATASCII values, and this tool is the translation layer that turns those numbers into words you can search, edit and archive.
- Recovering documents from ATR disk images. A rescued Atari word-processor file is a stream of ATASCII codes with 155 line endings. Decoding it here produces clean modern text, ready for a preservation archive or family history project.
- Reading BASIC program data. DATA statements in a typed-in Atari listing encode messages as numbers. Paste the values to see the hidden strings without booting an emulator and running the program.
- Debugging emulator memory dumps. An Atari emulator shows screen memory as raw codes while you hunt a display bug. Converting a region to ASCII reveals what text the program was actually trying to print.
- Transcribing magazine type-in programs. Verifying a 1980s magazine listing means checking the character data it embeds. Decoding sample sequences confirms your transcription matches the intended output before a full test run.

About the Convert ATASCII to ASCII tool
Convert ATASCII to ASCII runs as plain JavaScript in your browser tab, with no server behind it. Decode Atari ATASCII codes back into ASCII characters. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's ASCII Tools section, 81 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Convert ATASCII to ASCII free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
