Free Online JSON to CSV Converter

JSON to CSV conversion is the process of transforming hierarchical JSON data into a flat, tabular CSV (Comma-Separated Values) format. JSON (JavaScript Object Notation) stores data in nested objects and arrays, while CSV organizes data in rows and columns like a spreadsheet. This conversion is essential when you need to analyze JSON data in Excel, import it into databases, or share it with users who prefer spreadsheet formats. Our free online JSON to CSV converter makes this transformation seamless.

When you convert JSON to CSV, each object in a JSON array becomes a row in the CSV file, and each property becomes a column. For example, an array of user objects with properties like "name," "email," and "age" will produce a CSV with three columns and one row per user. This transformation makes complex API responses and database exports immediately usable in spreadsheet applications. This JSON to CSV converter tool handles all JSON structures automatically.

[
  {
    "id": 1,
    "name": "John Doe",
    "email": "john@example.com"
  },
  {
    "id": 2,
    "name": "Jane Smith",
    "email": "jane@example.com"
  }
]

id,name,email
1,John Doe,john@example.com
2,Jane Smith,jane@example.com

How the Conversion Works

• •Parsing: The JSON array is parsed and validated
• •Flattening: Nested objects are flattened using dot notation (e.g., user.address.city)
• •Header Extraction: All unique keys become column headers
• •Row Mapping: Each object's values are mapped to the corresponding columns
• •CSV Generation: Data is formatted with proper delimiters and escaping

The conversion process handles edge cases like nested objects, arrays within objects, missing properties, and special characters that need escaping in CSV format. This ensures your data maintains integrity while becoming more accessible for spreadsheet analysis, data science workflows, and business intelligence tools. Our JSON to CSV converter online ensures compatibility with all spreadsheet applications.

JSON to CSV conversion is particularly useful for developers working with APIs, data analysts who prefer spreadsheets, and teams that need to share structured data with non-technical stakeholders who are more comfortable with Excel or Google Sheets than raw JSON. Our free JSON to CSV converter enables this transformation without requiring any software installation.
