Convert temporary bin file to excel file using SDfat library


I am currently using lowlatencylogger example from SDfat library to log MPU6050 into microSD card.

Everything run smoothly except sometime I did not truncate the data and it does not save in csv file. So what I got is temporary bin file, which is unreadable.

So my question is, may I know how to convert this temporary bin file into csv file? Can I just use the lines in the lowlatencylogger example to convert them?

Thank you.
