À propos de CSV to JSON Converter

This tool converts CSV (Comma-Separated Values) data to JSON format. It auto-detects the delimiter (comma, semicolon, or tab), handles quoted fields with embedded commas and newlines, and supports first-row-as-headers for named object keys. Choose between array-of-objects output (each row becomes a JSON object) or array-of-arrays output (raw data). Configure indentation (2 or 4 spaces) for readability. Ideal for importing spreadsheet data into web applications, APIs, and databases.

Questions fréquentes

What delimiters does this support?
The tool auto-detects commas, semicolons, and tabs. It analyzes the first line of your input to determine which delimiter is most likely, so you don't need to select it manually.
How are quoted fields handled?
Fields wrapped in double quotes can contain commas, newlines, and other special characters without breaking the parsing. Double quotes within a field are escaped as two consecutive quotes (""), following the RFC 4180 standard.
What is the difference between 'Array of Objects' and 'Array of Arrays'?
Array of Objects uses the header row as property names: [{"name": "Alice", "age": 30}]. Array of Arrays returns raw rows: [["Alice", "30"]]. Objects are easier to work with in code; arrays are smaller and preserve the exact structure.
