Two different types of trc to csv conversion actually exist and although both are used for parsing of data from 'trace' files, these are from completely different solutions.
The first kind is for .trc files that come from software used to capture and analyze network packages and for these you have to use Wireshark or similar solutions.
A completely different type of .trc files comes from Teledyne LeCroy Oscilloscopes and for these you either have to rely on the WaveStudio software from LeCroy, some 3rd party solutions. Try to search for various parsers/readers n GitHub for example, just search the one that works for your needs best.
