  • Primary task: CSV encoding and delimiter fix guide.
  • Problem solved: A quick reference for fixing comma, semicolon, tab, quoting, and encoding problems before import.
  • Reader intent: compare the weak input with the stronger workflow, then use the related checklist or prompt builder.
  • Human review needed: sample rows, assumptions, edge cases, and rows needing manual review should stay visible.

Copy-ready prompt patterns

File structure checks

Verify the parser sees the file the same way you do.

  • Check delimiter choice.
  • Confirm UTF-8 or other encoding.
  • Inspect quote handling and line breaks.

Fix prompts

Use AI to isolate the breakage.

  • Find the most likely parsing failure.
  • List rows that may shift columns.
  • Recommend the safest re-export settings.

Rerun guardrails

Prevent the same import failure twice.

  • Keep raw and cleaned copies separate.
  • Log the chosen delimiter.
  • Test a small sample after each fix.

FAQ

How do I know if the CSV delimiter is wrong?

If the importer places multiple columns into one field or shifts values across rows, the file may be using a different delimiter than expected.

Why does UTF-8 matter for CSV import?

If the encoding is wrong, special characters, symbols, and names can be corrupted during upload.

Should I re-export the file or edit it manually?

Re-exporting from the source system is usually safer than trying to repair every parser issue by hand.
