I wonder if this is possible
I have a cluster of 3 arrays. I have easiy written the data of one array into csv file. I would like to write the data of other arrays written in
sheet 2 and sheet 3 of the csv file.
I used simple open, close file function and write txt file function with the file path ending in .csv and it had worked fine.
There is no concept of "sheets" for a .csv file. It is a "plain text" file that uses comma seperated values. If you are trying to write to a spreadsheet file (for example: Microsoft's Excel), then this is completely different and would also have a different file extension.
CSV (Comma Separated Values) files do not support multiple sheets. Each file is a sheet.
What they said. I'd also like to add that a relativly easy way to do this is to write your files as TDMS which does support 3 dimension data (not just rows and columns) and when using the free TDMS add-in it can open TDMS files into multiple tabs.
