How to use Convert EBCDIC to Binary
- 1. Paste your EBCDIC characters. Enter the characters you want encoded into the input pane, such as text extracted from a mainframe record or an old CP037 code page reference.
- 2. Set the Separator. Type the character to place between the resulting 8-bit binary values, so each encoded character's byte stays clearly separated from the next.
- 3. Copy the binary output. Copy the CP037-mapped binary bytes from the output pane into a mainframe file format note, a migration script, or documentation about legacy encodings.
When to use Convert EBCDIC to Binary
Convert EBCDIC to Binary maps characters through the CP037 code page used on IBM mainframes and outputs their binary byte values. It is aimed at anyone working with legacy mainframe data where ASCII assumptions do not apply.
- Migrating a mainframe data extract. You are moving fixed-width records off an IBM mainframe and need to confirm the binary byte values behind specific EBCDIC characters before writing a conversion script.
- Reverse engineering a COBOL file format. An old COBOL program produces files in EBCDIC and you want to verify how a particular field's characters map to binary before parsing the file elsewhere.
- Teaching the history of character encodings. You are explaining why EBCDIC differs from ASCII in a systems course and want to show students the actual binary values a letter takes under CP037.

About the Convert EBCDIC to Binary tool
Convert EBCDIC to Binary runs as plain JavaScript in your browser tab, with no server behind it. Convert EBCDIC characters to binary values. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Binary Tools section, 112 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Separator setting, and the result refreshes the moment you change it. 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 EBCDIC to Binary 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.
