JSON to CSV Converter Online
Convert JSON arrays to CSV format in one click. Perfect for spreadsheets, data exports, and report generation.
JSON is the standard format for APIs and web services, but spreadsheet tools like Excel and Google Sheets work best with CSV. Converting JSON to CSV lets you open API data in any spreadsheet tool, import into databases, or share with non-technical stakeholders.
When to Convert JSON to CSV
- Exporting API responses to Excel or Google Sheets
- Preparing data for import into PostgreSQL, MySQL, or Airtable
- Generating reports from JSON database exports
- Sharing structured data with teams who don't use JSON
Example
Input (JSON Array):
[
{ "id": 1, "name": "Rohith", "role": "admin", "active": true },
{ "id": 2, "name": "Priya", "role": "user", "active": false },
{ "id": 3, "name": "Arjun", "role": "user", "active": true }
]
Output (CSV):
id,name,role,active
1,Rohith,admin,true
2,Priya,user,false
3,Arjun,user,true
Nested JSON to CSV
Nested JSON is flattened automatically. For example:
[{ "user": { "id": 1, "name": "Rohith" }, "score": 9.5 }]
Becomes:
user.id,user.name,score
1,Rohith,9.5
Tips for JSON to CSV Conversion
- **Arrays of objects** work best — each object becomes a row
- **Consistent keys** across objects produce clean columns
- **Nested objects** are flattened with dot notation
- **Arrays as values** (e.g. tags) are joined or stringified
Paste your JSON into DevConvert and select CSV as the output format.
