CSV to JSON Converter
Convert CSV to JSON online for free. Paste your CSV and get clean, formatted JSON with automatic type detection and custom delimiter support.
About this tool
This tool parses your CSV text and maps each row to its JSON equivalent. Headers become object keys and rows become objects in a JSON array, preserving the original data hierarchy.
Converting CSV to JSON is especially useful when integrating tabular data into web applications, migrating legacy database exports, or consuming REST APIs that expect JSON payloads.
Use Cases
- Data MigrationConvert legacy database exports and spreadsheet files into JSON to load into modern NoSQL databases.
- API IntegrationTransform spreadsheet datasets into JSON payloads ready to be sent to REST API endpoints.
