JSON to CSV Converter — Open Your Data in Excel

JSON is great for APIs and developers. CSV is what Excel, Google Sheets, and every business tool understands. Convert between them instantly.

Why JSON to CSV Matters

APIs return JSON. Databases export JSON. But your manager, your accountant, and your data analyst all work in spreadsheets. JSON to CSV conversion bridges the gap between developer tools and business tools.

How It Works in Formly

1. Drag a .json file onto Formly
2. Formly automatically detects it as JSON and suggests CSV as the output
3. Click Convert — the JSON array is flattened into CSV with headers
4. Download the CSV — opens directly in Excel, Google Sheets, or Numbers

Example: JSON Input

[
  {"name": "Alice", "department": "Engineering", "salary": 95000},
  {"name": "Bob", "department": "Design", "salary": 82000},
  {"name": "Carol", "department": "Marketing", "salary": 78000}
]

Example: CSV Output

name,department,salary
Alice,Engineering,95000
Bob,Design,82000
Carol,Marketing,78000

Privacy: No Data Leakage

Many JSON-to-CSV converters are server-based — your data goes to someone else's computer for processing. Formly does the conversion entirely in your browser using JavaScript. Your JSON data never leaves your device. This matters if your JSON contains customer data, financial records, or proprietary information.

Other JSON Conversions

Formly also converts:

• JSON → XML (for legacy systems and SOAP APIs)
• CSV → JSON (reverse the flow — spreadsheet data back to API format)
• XML → JSON (modernize legacy XML data)
