Hi,
If you are using Write to Spreadsheet File VI, you can use "transpose?" input to write your 1D array as a column or as a row.
If you use ActiveX to send this array to a spreadsheet, you can transpose the array by using Transpose 2D Array function. You will first need to build your 1D array into 2D with the Build Array function. Look at the block diagram of Write to Spreadsheet VI to see how these 2 functions are used.
