As of late I found that going through SimConnect Logfiles to be quite time consuming. So I’ve made a weekend hack project which streamlined the format in order to gain more insight faster.
As I got support here in this forum I’d like to return some and made it available on Github in order to grow 
I just decoded the lines I found so far and there are likely some (many) which are not yet handled.
So either add them or let me know (Issue at github with an example line) so I can add as needed.
It consist of a decoding library and a demo app.
For now the demo app lists Opens and Disconnects
Traces Exceptions with the causing line (if found)
And singles out log entries of a selected client.
It can dump as JSON for other purposes.
May be it’s of use for some…
It should build without further dependencies in VS2022
