Frequently Asked Questions
What is CSV?
CSV (Comma-Separated Values) is a plain-text format where each line represents a row of data and values are separated by commas. It is widely used for spreadsheet data, database exports, and data interchange between applications.
How are quoted fields handled?
Fields that contain commas, newlines, or double quotes are enclosed in double quotes. A literal double quote inside a quoted field is escaped by doubling it (e.g. "say ""hello"""). This converter fully supports RFC 4180 quoting rules.
When should I use JSON instead of CSV?
JSON is better when your data has nested structures, mixed types, or needs to be consumed directly by a JavaScript application or API. CSV is more compact and universally readable by spreadsheet tools like Excel or Google Sheets.
