EBCDIC-Konverter

EBCDIC (Extended Binary Coded Decimal Interchange Code) is IBM's proprietary character encoding, used on mainframe and midrange systems since the 1960s. Unlike ASCII, which maps characters to a logical sequence, EBCDIC's character assignments reflect the physical encoding of the IBM punch card. If you work with mainframe data exports, legacy financial systems, or IBM AS/400 integrations, you will encounter EBCDIC-encoded files that look like garbage until converted.

This tool converts EBCDIC hex sequences to readable ASCII text and encodes ASCII text to EBCDIC hex. It is indispensable for developers integrating with legacy IBM systems, data engineers migrating mainframe records to modern databases, and anyone debugging an FTP transfer from a z/OS system where the character encoding was not auto-converted.

EBCDIC online in ASCII konvertieren

1. 1

   EBCDIC-Hex oder ASCII-Text einfügen

   Fügen Sie einen EBCDIC-Hex-Dump zum Dekodieren in ASCII ein, oder geben Sie ASCII-Text zum Konvertieren in EBCDIC-Hex ein.

2. 2

   Sofortige Konvertierung

   Das Tool ordnet Bytes mithilfe der IBM Code Page 037 (US-Englisch EBCDIC) zu. Nicht zuordenbare Bytes werden mit ihrer Position markiert.

3. 3

   Ergebnis kopieren

   Kopieren Sie den konvertierten ASCII-Text oder die EBCDIC-Hex-Ausgabe für Mainframe-Workflows.

How EBCDIC Encoding Works

EBCDIC assigns 8-bit code points to characters but uses a completely different mapping than ASCII. The letter 'A' is `0xC1` in EBCDIC but `0x41` in ASCII; a lowercase 'a' is `0x81` in EBCDIC but `0x61` in ASCII. The alphabetic characters are not even contiguous — there are gaps in the EBCDIC sequence between 'I' and 'J' and between 'R' and 'S' — which famously breaks C programs that assume `'Z' - 'A' == 25`.

There are many EBCDIC variants (IBM Code Page 037, 500, 1047, and others) with different assignments for bracket characters and national currency symbols. The correct conversion table depends on the specific IBM system and region. This tool uses EBCDIC 037 (the US English variant most commonly used in North American mainframe data exports) as the default code page.

EBCDIC Converter vs. iconv vs. dd

The `iconv` command-line tool with the `EBCDIC-US` or `IBM037` encoding handles EBCDIC conversion well on systems where those code pages are installed, but availability varies and the command syntax is non-obvious. The Unix `dd` utility with `conv=ascii` does a basic EBCDIC-to-ASCII conversion but uses a fixed translation table with no code page selection. A browser-based converter is faster for quick inspection of a hex dump and works without any installed tools or knowledge of iconv code page names.
