TL;DR: Start strict on a sample, apply minimal fixes, then scale only after validation passes.

Decision matrix

Criteria exact parser error triage broad formatting cleanup
Best when You need strict, repeatable output You need rapid triage on messy input
Risk profile Lower hidden-issue risk, more upfront checks Higher hidden-issue risk, faster initial pass
Typical speed Slower first pass, faster downstream debugging Faster first pass, may need rework later
Good for Stable JSON pipelines One-off fixes and incoming unknown formats
Avoid if Input is heavily malformed and urgent turnaround is required You need audit-grade guarantees

Choose exact parser error triage when

  • You need deterministic results for repeated JSON runs.
  • You are fixing production data where hidden breakage is costly.
  • You want clear pass/fail criteria before conversion or export.

Choose broad formatting cleanup when

  • You are in early triage and need to narrow the problem quickly.
  • You are dealing with mixed-quality inbound files from multiple sources.
  • You need an iterative cleanup loop before strict validation.

Recommended no-upload workflow

  1. Validate a representative sample first. Confirm exact error class/position.
  2. Pick workflow A or B. Use strict path for quality, flexible path for triage.
  3. Apply the smallest safe fix. Avoid broad rewrites before validation is green.
  4. Re-validate and convert/export. Only then run batch processing.
