Convert EBCDIC - Ascii and Ascii to EBCDIC

Paste EBCDIC hex like E3F3F2F0F6F4, then press Convert.

EBCDIC to ASCII conversion

EBCDIC (Extended Binary Coded Decimal Interchange Code) is used on IBM mainframes and many card-scheme / ISO8583 host messages. Each byte is an EBCDIC code point; this tool maps that byte to ASCII using code page CP037. Digits are F0–F9, uppercase letters start at C1, and space is 40.

JavaScript

// EBCDIC CP037 hex "E3F3F2F0" -> ASCII "T320"
function ebcdicHexToAscii(hex) {
  hex = hex.replace(/\s/g, '');
  var out = '';
  for (var i = 0; i < hex.length; i += 2) {
    var b = parseInt(hex.substr(i, 2), 16);
    out += EBCDIC_TO_ASCII[b] || '';
  }
  return out;
}

Java

String ebcdicHex = "E3F3F2F0F6F4";
byte[] ebcdic = javax.xml.bind.DatatypeConverter.parseHexBinary(ebcdicHex);
String ascii = new String(ebcdic, java.nio.charset.Charset.forName("IBM037"));

C / iconv

iconv_t cd = iconv_open("UTF-8", "IBM037");
iconv(cd, &inbuf, &inbytes, &outbuf, &outbytes);
