How i can split an array in half?

Hello, i am creating a online database, so i want to write a large array (72x42) in google sheets then read it again with construct, but when i want to do it, google sheets mark error, cause the size of the array.

the thing is that i discovered, that if i use only a 36x21 array google sheets let me write it, but i don't know how to split the array in half and after that merge them together again.

it's there a way to make this work?

72x42 is not large. I work with data sets with 10,000x100 cells or more regularly in Construct. It would be easier to help if you showed what you did. I imagine if you just ran a loop to update one cell at a time you wouldn't have any issues.

i already solved it, the problem was in the AJAX plugin, it doesn't let me write to much information in one event in this case 15kb, i split the array thanks to "for" action, and i send the data in to AJAX events, thanks for worrying anyways.
