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.

Common failure cases
FAQ
If the importer places multiple columns into one field or shifts values across rows, the file may be using a different delimiter than expected.
If the encoding is wrong, special characters, symbols, and names can be corrupted during upload.
Re-exporting from the source system is usually safer than trying to repair every parser issue by hand.
