Q: Utility for FIX to verify message Anyone aware of a FIX utility available online to verify fix messages? ie: accept a fix message and check things like body length length and checksum.
thanks

A: There is a fix log decoder on https://fixspec.com. When you enter a message it is parsed and items such as checksum and body length are also checked. You need to register to access it, but registration is free.

A: https://drewnoakes.com/fix-decoder/ is a nice online FIX decoder that supports Checksum(9) and BodyLength(8) tags validation. 
No registration required.

A: One that I know of is ValidFix. There was a link to it on the QuickFix website, but it seems to be missing.

A: There's a licensed tool called VeriFIX http://www.greenlinetech.com/products/verifix.php.
Pasting it incase if it's useful to you or others.
