TL;DR: Validate -> locate exact failing spot -> fix the minimal part -> re-validate.

Execution steps

Validate input locally. Start with a validator or parser-friendly converter.
Locate root cause. Use line/position/error token to isolate one failing place.
Apply a minimal fix. Do not refactor all content at once.
Re-validate and continue. Once clean, convert/export safely.
