I would like to dynamically alter/add new headers to a csv file as needed. The code I have below overwrites the previously written data an amount equal to each new header added each time I call the vi below. Any suggestions on how to do this without reading in the file each time? I want to avoid the processing time of reading in the file between processing new data.
Thanks!

The simple answer is No.
You need to read the entire file to pre-pend that line.
If you were actually working with true Excel files, you can.

Thanks! That's what I thought.

If you're gonna change the file several time during a run you can ofc. keep the data/file in memory and modify that instead.

The problem with that is for days of testing you might loose data if something goes wrong.

Yes, but you can still write everytime, you dont need to read the file back. 🙂
