A convenient and powerful decoder for FIX messages.
All processing is done locally in your browser, so no one can snoop on your messages.
Unlike the most prominent online FIX message decoder, this version is open source so you can prove that your messages are safe. This version supports a wider range of message representations too, including multiple messages.
For example, you can paste directly from a QuickFIX log:
<20121206-12:04:56, FIX.4.2:MyComp->YourComp, outgoing> (8=FIX.4.2 9=189 35=AE 34=510 49=MyComp 52=20121206-12:04:56.898 56=YourComp 22=4 31=157.8 32=10 43=N 48=GB00B16GWD56 60=20121206-12:04:56.891 64=20121206 150=0 570=N 571=TRADE_ID_88871 828=0 918=GBX 10=028 )
<20121206-12:05:06, FIX.4.2:MyComp->YourComp, incoming> (8=FIX.4.2 9=119 35=AR 49=YourComp 56=MyComp 34=753 52=20121206-12:05:08 370=20121206-12:04:58.744 571=TRADE_ID_88871 150=0 939=0 10=106 )
Note the leading text is ignored, and that there are multiple messages.
Also the non-printable SOH character (\001) is handled correctly.
Using pipe characters (|) as separators is also supported.
