this opens the ledger live dir and there you have to look at a file called app.json (not accounts.json). its only usable if you have not encrypted your ledger live.
Thanks, it seems I followed a wrong guide then. Will try to check it later. Tbh this does not really matter to me because Bitcoin is not taxed in my country, but it's probably a good thing to have.
Theoretically, it should be a relatively simple task to import that json into a script and get it to output the transaction history into a .csv format of your choice.
Yeah, there are some JSON to CSV converter on the internet too. Never tried anything though.
