About CSV & JSON Conversion
CSV (Comma-Separated Values) is the universal format for spreadsheet and database exports. Converting CSV to JSON makes data ready for REST APIs, AI model training, JavaScript applications, and NoSQL databases. Converting JSON to CSV makes it easy to open in Excel, Google Sheets, or import into SQL databases.
Frequently Asked Questions
What JSON format does this produce?
CSV is converted to a JSON array of objects, where each row becomes an object with keys from the header row. For example: [{"name":"Alice","age":"30"},{"name":"Bob","age":"25"}]
How are quoted fields handled?
Fields enclosed in double quotes are handled correctly, including commas and newlines within quoted fields. This follows the RFC 4180 CSV standard.
Can I convert JSON arrays with nested objects?
Nested objects are serialized as JSON strings within the CSV cell. For flat JSON arrays (one level deep), the conversion produces clean CSV with proper column headers.
