When you collect performance data from perfmon you have a choice to save the file as a certain format. The most common format I run across is .blg. This format works great when you looking at the performance data through perfmon. Sometimes though it would be nice to pull this data into excel or another program in order to manipulate the data. This is were the program from Microsoft called Relog can be used. It has to be run from the command prompt. Below is the command that would need to be run in order to convert a .blg file to a .csv file. The process is quick and easy.
relog filname.blg -f CSV -o newfile.csv
