Remove JSON comments safely (no upload)
Many configs allow comments, but JSON.parse does not. Learn safe removal strategies and validation steps.
JSON comments are not allowed
Fix JSON comments are not allowed. Validate strict JSON locally, pinpoint the exact break, then format/repair and re-validate (no upload).
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
