I think you can use Array to spreadsheet String to convert 2D array into string , then just use write file.
I use the file primitives these days because this method has a couple advantages.
Hey guys, looking to continuously write data to a spreadsheet. I know the Write Delimited to File would work well here, but I am using 2014 version and do not have.
The old version of the Write Delimited Text File was the Write To Spreadsheet File VI. But since you are continuously writing data, use the primitives as already stated. Use Array To Spreadsheet String to convert your data into a string and then write that string with Write To Text File. Open/Create the file before your loop and close it after the loop.
