Unterminated string in JSON Playbook

Unterminated string in JSON. Step-by-step no-upload workflow: validate, locate root cause, fix quickly, and verify.

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

Execution steps

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