Convert ADR to JSON

QUICK ANSWER
Is it possible to convert ADR to JSON?
Yes - ADR converts to JSON.

No direct converter; convert to HTML first (via Opera 12), then import into Chrome/Edge which stores bookmarks as JSON internally. Alternatively, small Python/Node scripts can parse the INI-like ADR format and produce JSON.

Also to JSON: BDOB · EXPRESS · REPLIT
