JSON to CSV Converter
Convert JSON data to CSV format. Paste JSON or upload a file and get a downloadable CSV.
What This Tool Does
Converts JSON arrays to CSV format in your browser — handles flat arrays, nested objects (flattened to dot-notation columns), and arrays of objects. No upload, no server processing.
Who This Is For
- Data analysts who receive JSON API responses and need to open them in Excel or Google Sheets
- Developers exporting structured data from a NoSQL database for reporting
- Business users who need to turn an API response into a spreadsheet without writing code
- QA engineers converting test fixture JSON into CSV for data-driven test frameworks
Example: Input: A JSON array of 500 objects with fields like {"id": 1, "name": "Alice", "email": "..."} → Output: A CSV with headers id,name,email and one row per object, ready to open in any spreadsheet app
💡 If you need the reverse operation — importing a CSV into a JSON structure — use the CSV to JSON converter. For working with the JSON before converting, the JSON Formatter makes it readable and validates syntax. Need to share the resulting spreadsheet as a fixed-layout document? Try Excel to PDF.

Handling Nested JSON in CSV Export
Flat JSON arrays convert to CSV straightforwardly — each object becomes a row, each key becomes a column header. Nested JSON requires a strategy choice:
- Flatten nested objects — a nested key like
address.citybecomes a column named "address.city" or "address_city". This is the most common approach. - Stringify nested values — the nested object is serialized back to a JSON string and placed in a single cell. Useful when the nested structure should be preserved.
- Ignore nested objects — only top-level scalar values are exported. Nested objects and arrays are dropped.
- Expand arrays into rows — if an array field contains multiple items, each item generates a separate row with the parent record repeated.
The right approach depends on how the CSV will be used. For spreadsheet analysis, flattening is usually best. For importing into another system, check what format that system expects.
CSV Delimiter Options: Comma, Tab, Semicolon
CSV stands for "comma-separated values" but the actual separator varies by locale and use case:
| Delimiter | Use Case | Notes |
|---|---|---|
| Comma (,) | Default, international standard | Avoid when values contain commas (addresses, descriptions) |
| Semicolon (;) | European locale default | Excel in Germany/France defaults to semicolons due to comma as decimal separator |
| Tab (\t) | TSV format, database exports | Best when values may contain commas or quotes; clean to import |
| Pipe (|) | Legacy data formats | Used in some database dumps and EDI formats |
Data Export and Analysis Tools
JSON to CSV opens up spreadsheet analysis — pair it with these tools:
- Convert CSV back to JSON — reverse the process
- Validate the source JSON before converting to catch structural issues early
- Format the JSON for review before exporting
- Convert to XML instead if your import target requires XML
- Generate test JSON data to validate your CSV export workflow
Frequently Asked Questions
How It Works
When to Use This Tool
- →Exporting API response data to Excel or Google Sheets for analysis
- →Sharing structured JSON data with non-technical stakeholders who work in spreadsheets
- →Converting a JSON data export from a database or API into a format for reporting tools
- →Preparing JSON data for import into a system that only accepts CSV
🔒 Privacy & Security
JSON is parsed and converted to CSV entirely in your browser's JavaScript engine. No JSON data is uploaded. For JSON containing user data, API keys, or business data, local processing prevents any exposure.
