I'm making few measurements and would like to write this scalar value in excel. It seems that all Vi uses 2D array. I've used XL "append table to report" related vis. I can not provide 2D arrays in each case. How can write "DBL" to XL?
If you look a little deeper into the shipping example called Write Table TO XL, you'll see a subVI called Set Cell Value. This is inside a for loop which is how a 2D array gets written. Use the subVI by itself to update a specific cell.
