How to clear datalogger log

I have been using the datalogger extension in MakeCode blocks and have collected my data. Now, I can’t seem to clear the log to start new. I have created new code in a new program, using the datalogger extension and it keeps adding to the bottom of the same spreadsheet. I have tried deleting the log file, renaming the log file, resetting the CPX, changing the variables in the code, deleting all the content in the log file…etc. I can’t delete the old data and any new data is just added to the bottom of my spreadsheet. Any suggestions?
