The Logfile Navigator is a TUI for viewing/analyzing log files and will pretty-print anything with a keypress, see https://lnav.org/features#pretty-print-view https://lnav.org/features#pretty-print-view It's not specific to JSON/XML either, it works on any text that follows the usual conventions for structuring data in a textual way. You can filter by level as well, but, usually I just press e/E to jump to the next/previous error from the current location. There are, of course, many other features as well.
