Tips & Troubleshooting
These quick notes help you get clean, reliable results with Convert Excel to CSV — export clean datasets from XLSX—especially when you’re uploading to forms, emailing files, or preparing documents for submission.
Best results
- Use UTF‑8 encoding when converting CSV/JSON so special characters stay intact.
- Standardize headers before converting—consistent columns prevent broken outputs.
- Export a small sample first to confirm the formatting before converting a large file.
- After conversion, open the output once to confirm columns, dates, and decimals.
Troubleshooting
- If columns shift in CSV, values may contain commas—ensure they are quoted properly.
- If JSON is nested, flattening may be needed before conversion to CSV.
- If dates change formats, set the column format in Excel after import.
- If output looks garbled, re-save your source as UTF‑8 and retry.
Privacy
