I want a quick way to read a file, as I dont want to spend weeks of syncing. Anyone here with technical experience, I mean real experience like know how to read a DB format, not just copy&paste github repos.
I don't know how often you want to hear it..
Install core and load your wallet.dat into it. You do NOT NEED to sync the blockchain.
Then simply check the addresses on a block explorer or import the private keys directly into electrum.
This takes 5 minutes maximum. The fact that you are still asking the same question after 20 days shows that you don't even appreciate any suggestions.
I wouldn't expect anyone else to help you with this if you don't want to accept the fastest and easiest approach.
