Frequently Asked Questions
What format should my CSV be in?
Standard CSV with comma-separated values and a header row works best. The first row is used as JSON keys and each subsequent row becomes a JSON object in the output array.
Are quoted fields with commas handled correctly?
Yes. Fields wrapped in double quotes (e.g., "Smith, John") are parsed correctly, preserving the comma as part of the value rather than treating it as a delimiter.
What happens with empty cells?
Empty cells are converted to empty string values in the JSON output. You can handle null mapping manually after conversion if needed.
Can I use tab-separated values (TSV)?
Some configurations support TSV. If your data is tab-separated, try replacing tabs with commas before pasting, or use the raw paste mode if available.
