About CSV ↔ JSON Converter
CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) are two of the most common data interchange formats. CSV is widely used in spreadsheets and databases, while JSON is the standard for APIs and web applications. This tool converts between the two formats with support for custom delimiters and header row detection.
How to Use
Paste your CSV or JSON data in the input area. Select the delimiter (comma, semicolon, tab, or pipe) and whether the first row contains headers. Click "CSV → JSON" or "JSON → CSV" to convert. Copy the result with one click.
Common Use Cases

- •Transforming API responses (JSON) to CSV for Excel or Google Sheets
- •Preparing data for database imports from different source formats
