Encoding issues in CSV/JSON: UTF‑8, BOM, and weird characters
Fix encoding issues like UTF‑8 BOM, strange header characters, and broken symbols in CSV/JSON. Convert locally and validate output (no upload).
UTF-8 BOM breaks JSON parsers: exact parser error triage vs broad formatting cleanup
UTF-8 BOM breaks JSON parsers: when to choose exact parser error triage vs broad formatting cleanup, with a safe no-upload decision workflow.
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
- Validate a representative sample first. Confirm exact error class/position.
- Pick workflow A or B. Use strict path for quality, flexible path for triage.
- Apply the smallest safe fix. Avoid broad rewrites before validation is green.
- Re-validate and convert/export. Only then run batch processing.
