- • Comma-separated values
- • Values with commas must be quoted
- • Will create an array of JSON objects

Frequently Asked Questions
What is JSON and when should I use it?
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate. Use JSON for APIs, configuration files, and data storage where hierarchical structure is important.
What is CSV and when should I use it?
CSV (Comma-Separated Values) is a simple file format for tabular data. Use CSV when you need to work with spreadsheet applications like Excel, import data into databases, or share data in a universally compatible format.
How do I convert JSON to CSV?
Paste your JSON data (must be an array of objects or a single object) into the input field, select "JSON → CSV" mode, and click Convert. The tool will generate a CSV with headers from your JSON keys. You can then copy or download the result.
Can I convert CSV back to JSON?
Yes! Switch to "CSV → JSON" mode, paste your CSV data (with headers in the first row), and click Convert. The tool will create a JSON array of objects where each row becomes an object with keys from the header row.
Is my data safe when using this converter?
Absolutely! All conversion happens entirely in your browser. Your data never gets sent to our servers or anywhere else, ensuring complete privacy and security of your information.
Best Practices & Tips
For JSON to CSV:
- Ensure all objects in your array have the same keys for consistent CSV headers
- Flatten nested objects before conversion for better CSV compatibility
- Use simple data types (strings, numbers, booleans) rather than complex objects
- Validate your JSON syntax before conversion to avoid errors
For CSV to JSON:
- Always include a header row with column names
- Avoid special characters in headers for cleaner JSON keys
- Use quotes around values containing commas or line breaks
- Ensure consistent number of columns across all rows
