Is there any way I can append waveform data that are being exported to excel without creating new file? See description below. (code attached)

I have a waveform with data from 1 to 5 and I would like to export all these data to excel every 60 seconds I set. I'm being able to do it successfully. I just don't like how I'm creating new files every 5 seconds. Is there a way to append the data as shown below. Just one file with all the data.

You have to use explicit functions. As you can tell, "export to excel" has no configuration options and is typically used by right-clicking, not via code.

Why not do plain tab delimited text and append to file? Much less overhead!
