JSON to CSV Converter — Free Online, No Signup

How to use

1. Paste JSON — Enter your JSON array data
2. Convert to CSV — Conversion happens automatically
3. Download CSV — Copy or download your CSV file

What Does This Tool Do?

This free online converter transforms JSON arrays into CSV (comma-separated values) format. JSON is how APIs and web applications store data. CSV is what spreadsheets and databases understand. This tool bridges the gap between the two.

When Would You Need to Convert JSON to CSV?

Data often comes in JSON format, but you need it elsewhere:

• API exports: You pulled data from a REST API and need to analyze it in Excel.
• Database imports: Your target system accepts CSV but your source provides JSON.
• Report generation: Management wants spreadsheets, not JSON files.
• Data migration: Moving data between systems that speak different formats.
• Quick analysis: Google Sheets is faster for exploring data than writing code to parse JSON.
• Sharing with non-technical colleagues: Everyone can open a CSV; not everyone knows JSON.

How Does It Work?

Paste your JSON array (e.g., [{"name": "John", "age": 30}, {"name": "Jane", "age": 25}]) into the input area. The tool automatically extracts all keys to create column headers. Each object becomes a row. Special characters are properly escaped. The result is valid CSV ready for download or copying.

Format Requirements

The tool expects a JSON array of objects. Each object represents a row, and each key becomes a column. Nested objects are converted to their string representation. For best results with deeply nested data, flatten it first or use a different approach.

Who Uses This Tool?

Business analysts exporting API data to spreadsheets. Developers creating data dumps for clients. Data scientists preparing datasets. Marketing teams analyzing campaign data. Product managers creating reports from analytics APIs.

Error Handling

If your JSON is invalid, the tool will show a clear error message. Common issues include missing brackets, trailing commas, or unquoted strings. Fix the JSON syntax and try again.

Secure by Design

Conversion happens in JavaScript on your machine. No data leaves your browser — essential when handling API responses containing customer records or business information.
