Frequently Asked Questions
How does CSV to JSON conversion work?
Our tool parses CSV data (comma, tab, or semicolon separated), auto-detects headers from the first row, and converts each row to a JSON object. It handles: quoted fields, escaped commas, empty values, and multi-line fields.
Can I customize the output format?
Yes! Options include: use first row as headers (or generate keys), convert numbers automatically, handle boolean values (true/false, yes/no), and choose output format (array of objects, object of arrays, or nested JSON).
What if my CSV has commas inside quotes?
Our parser correctly handles RFC 4180 CSV format, including: commas inside double quotes, escaped quotes (""), and line breaks within quoted fields. This is essential for data with addresses, descriptions, or multi-line content.
