First, they do not say if the CPU is in a plug in socket so it can be changed out but it is possible. This is what you will need to confirm first if you are planning on changing out the processor. You do not say which processor you have currently. Here is your support page:

https://support.hp.com/us-en/docume...

Here is the list of supported processors from that page:

3rd Generation Intel Core i7-3612QM (2.1 GHz, 6MB L3 cache, 4 cores)2
Up to 3.10 GHz with Intel Turbo Boost Technology
3rd Generation Intel Core i5-3360M (2.8 GHz, 3MB L3 cache, 2 cores)2
Up to 3.50 GHz with Intel Turbo Boost Technology
3rd Generation Intel Core i5-3320M (2.6 GHz, 3MB L3 cache, 2 cores)2
Up to 3.30 GHz with Intel Turbo Boost Technology
3rd Generation Intel Core i5-3210M (2.5 GHz, 3MB L3 cache, 2 cores)2
Up to 3.10 GHz with Intel Turbo Boost Technology
3rd Generation Intel Core i3-3110M (2.4 GHz, 3MB L3 cache, 2 cores)2
Up to 3.10 GHz with Intel Turbo Boost Technology
2nd Generation Intel Core i5-2450M (2.5 GHz, 3MB L3 cache, 2 cores)2
Up to 3.10 GHz with Intel Turbo Boost Technology
2nd Generation Intel Core i3-2370M (2.4 GHz, 3MB L3 cache, 2 cores)2
2nd Generation Intel Core i3-2350M (2.3 GHz, 3MB L3 cache, 2 cores)2
2nd Generation Intel Pentium B980 (2.4 GHz, 2MB L3 cache, 2 cores)
2nd Generation Intel Pentium B970 (2.3 GHz, 2MB L3 cache, 2 cores)
2nd Generation Intel Celeron B840 (1.9 GHz, 2MB L3 cache, 2 cores)

Changing out what you have (if possible) and how much you may benefit from it is dependent on what you currently have and how cheaply you can get something better. The bigger the step up, the more you may see some improvement.

You also should first consider how much memory you have. If you have the minimum amount of memory then you wil see a significant improvement in speed and responsiveness if you maximize your memory. With large Excel files you are using a large amount of memory, if you run low on memory your system is using virtual memory which is a reserved portion of your hard drive to supplement the memory which is much slower. If the virtual memory is not set high enough for your use then it will slow down even more. Here is your memory specs:

Standard
DDR3 PC3-10600 SDRAM (1333 MHz)
Two SODIMM slots supporting dual-channel memory.
2GB and 4GB SODIMMs
Maximum
Upgradeable to 8192MB with optional 4096MB SODIMMs in slots 1 and 2.
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.

If you purchase a matching pair of compatible 4GB memory sticks (compatible laptop memory) (assuming you have 64bit Windows) you will see a REALLY big improvement for not very much trouble or expense. You can also increase the virtual memory amount to at least the same size as your actual memory for possible further improvement.

Another upgrade you should consider before a CPU upgrade is to swap out your hard drive for an SSD drive and clone the drive over to it. This will offer significant improvement in performance ESPECIALLY in loading the program and its data into memory when launching it and again when saving changes to it.

You have to be a little bit crazy to keep you from going insane.

We don't know how you use your laptop or how well you maintain it, but uninstalling unnecessary programs, managing start-up apps, purging temp internet & history files, scanning for viruses & malware, should be done regularly. I agree with Fingers that the CPU probably isn't the upgrade you need. More RAM & switching from a mechanical HDD to a SSD will definitely improve performance, but I would start with a thorough cleaning.
