VBA’s Error 7 (Out of Memory) occurs when your system runs out of resources to back up Excel to execute the macro. When you open an application in your system that takes a part of the resource and when you have to try to execute a macro and the resource that you have is not sufficient, you get the error 7.
Apart from that, there are a few points that you need to check when facing this error (Out of Memory).
- As I said, you could have a lot of applications running which makes the system run on the memory. You can close all those applications that are unnecessary.
- You have a lot of lengthy codes in the same module. You can try to use different modules for all those codes.
- Windows run out of virtual memory.
Below I have shared a few links that can help you to deal with this error.
