Complete Guide: How to Use the JSON to CSV Converter
Convert JSON data to CSV format instantly. Our converter handles nested objects, arrays, and complex JSON structures, flattening them into clean CSV tables. Perfect for moving data between APIs and spreadsheet applications. All conversion happens in your browser — your data stays private.
Step-by-Step Instructions
- 1
Paste your JSON data
Enter a JSON array of objects (the most common format from APIs). Each object becomes a CSV row, and each key becomes a column header.
- 2
Configure options
Choose delimiter (comma, semicolon, tab), whether to include headers, and how to handle nested objects (flatten or stringify).
- 3
Preview the CSV
See the converted CSV in a preview table before downloading. Check that columns and values look correct.
- 4
Download the CSV
Download the CSV file or copy it to clipboard. The file uses UTF-8 encoding with BOM for Excel compatibility.

Frequently Asked Questions
What JSON format is supported?
The converter works best with a JSON array of objects — e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Each object becomes a row and each key becomes a column header.
What happens if objects have different keys?
The converter collects all unique keys across every object and uses them as column headers. If an object is missing a key, the cell is left empty in the CSV output.
Can I convert nested JSON?
Nested objects and arrays are serialized as JSON strings in the CSV cell. For best results, flatten your JSON before converting.
Is there a size limit?
Everything runs in your browser, so there is no server-side limit. Very large files (100 MB+) may slow down depending on your device.
Is my data safe?
Absolutely. The conversion happens entirely in your browser. No data is uploaded to any server.
