Hi, whenever I run this code my data get updated to the last file data. I don't want to do it, rather I want all data to stack one after another. How can I update this code?

We can't run images and I'm not going to type all that in. I suspect you want output to change depending on what "j" is but you're not using j as an index to "output". Why not? Maybe it should. Not sure what "stacked" means. You're assigning data to a 2-D array. Do you want a 3-D array? What exactly does "stacked" mean to you? Can you provide a small and simple example of input and output data?
