How do I actually validate a bitcoin block's hash


My assumption is that I can download a block, it's time stamp and the entire list of TXs and use comand line to hash it using sha256 algorithm and get the same 0000... hash thats on any explorer.

I checked blockchain com, and a few other online blockchain viewers but I'm strugling to actualy find clean csv or smth to download that I could use for hashing.

Googling gives me some basic 101 on tx verification but not specifically what I need. Any one can guide me to the right direction?

I just want to ceck one hash out of curiosity.
