Convert JSON to CSV

Transform JSON data into CSV format for use in spreadsheets, databases, and data analysis tools. Our free converter handles complex JSON structures and outputs clean, importable CSV.

**What is JSON to CSV Conversion?**

JSON arrays of objects convert naturally to tabular CSV format. Object keys become column headers, and each object becomes a row. This makes JSON data usable in Excel, Google Sheets, and database imports.

**Example Conversion:**

JSON Input:
[
{"name": "John", "age": 30, "city": "New York"},
{"name": "Jane", "age": 25, "city": "Los Angeles"}
]

CSV Output:
name,age,city
John,30,New York
Jane,25,Los Angeles

**Use Cases:**
- Export API data to spreadsheets
- Prepare data for database import
- Convert web app data for reporting
- Migrate between data systems
- Create data exports for clients

**Handling Complex JSON:**

**Nested Objects:**
Nested properties are flattened with dot notation. {"user": {"name": "John"}} becomes a column named "user.name".

**Arrays:**
Array values can be joined as comma-separated strings or expanded into multiple rows, depending on your preference.

**Mixed Schemas:**
Objects with different properties are handled gracefully. Missing values become empty cells in the CSV.

**CSV Options:**
- Custom delimiter (comma, semicolon, tab)
- Quote all values or only when necessary
- Include or exclude headers
- Handle null values
