Should be fine. I have a MSI Z690 Carbon EK X+ 2x16gb Trident Z 6400mhz and will upgrade to 2x48gb same sticks.

Lol what i skipped

I7 3770 --> I912900k DDR3 1600 --> DDR5 6400 GT630 --> GTX 1050 --> RTX 2080s (while waiting for release of 4090) --> 4090

I have a 12900k with 2x16 GB RAM and 4090 will upgrade to 2x48gb and i often use over 200+ Tabs in chrome. Not all Excel but some are. 12900k i no problem for it so 14700k should be fine but If money doesn’t matter go AMD Threadripper with 2x 64 core CPU

The question is what Resolution do you use? 1080p, 1440p or 2160p I mean If you want the best for gaming, streaming and more… 14900k + 4090 + 2-4x 48gb sticks.
