About this tool
CSV looks simple until a field contains a comma, a quote, or a line break inside quotes — a naive split-on-comma approach breaks on all three. This tool uses a proper CSV parser under the hood, so quoted fields containing commas, and escaped quotes written as a doubled `""`, are both handled correctly rather than silently corrupting your data.
The first row is always treated as the header row and becomes the key names in each resulting JSON object; every subsequent row becomes one object in the output array.
Frequently asked questions
As long as the field is properly quoted in the CSV (like `"Smith, John"`), the comma inside the quotes is preserved as part of the field and not treated as a column separator.
