Anybody good with excel? Looking to split a single sheet into several sheets/workbooks for easier alignment.

Hello,

I have a pair of 16 page excel files that I want to align but due to their length, they're extremely laggy in the align view. The pages are manually split in this way and I'd like to break them up into different files and align the multiple files. I've downloaded Kutools for excel but I get an error when I try to split a sheet. 

Best regards,

Keenan
