Fix CSV newlines (CRLF vs LF) before converting (no upload)
How Windows (CRLF) vs Unix (LF) line endings affect CSV parsing, and practical fixes before converting locally.
CRLF vs LF line endings in CSV: comma-delimited exports vs semicolon/tab-delimited exports
CRLF vs LF line endings in CSV: when to choose comma-delimited exports vs semicolon/tab-delimited exports, 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 | comma-delimited exports | semicolon/tab-delimited exports |
|---|---|---|
| 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 CSV 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 comma-delimited exports when
- You need deterministic results for repeated CSV runs.
- You are fixing production data where hidden breakage is costly.
- You want clear pass/fail criteria before conversion or export.
Choose semicolon/tab-delimited exports 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.
