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

  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.
