What this CSV to JSON converter does
Parses CSV with a header row into a JSON array of objects. Handles quoted fields, commas inside quotes, escaped quotes, and multiline cells correctly.
Common pitfalls handled
Most CSV data contains commas inside quoted fields or values that span lines. This converter follows the standard CSV rules, so "hello, world" stays one field and newlines inside quotes survive the conversion.
