How To Convert JSON to CSV
Paste Your JSON
Copy your array of JSON objects and paste it directly into the input editor on the left side.
Convert Data
Click "Convert to CSV". The tool parses your data and builds the CSV structure using the keys from the first object.

Your clean CSV data will appear on the right. Copy it to your clipboard or download it as a .csv file.
Key Features
Automatic Headers
Intelligently detects keys from your JSON data to generate accurate column headers for your CSV file automatically.
Smart Escaping
Handles special characters, commas, and quotes within your values by properly escaping fields to ensure the CSV remains valid.
Secure & Client-Side
Your data never leaves your browser. All conversion happens locally via JavaScript, guaranteeing complete data privacy.
Frequently Asked Questions
The input must be a JSON array of objects (e.g., `[{"name": "A", "age": 25}, {"name": "B", "age": 30}]`). A single object without square brackets will not convert correctly to a multi-row CSV.
The tool automatically wraps fields containing commas, quotes, or newlines in double quotes (e.g., `"New York, NY"`). This standard CSV escaping ensures Excel reads the data as a single cell.
The CSV headers are generated based on the keys of the first object in the array. If subsequent objects have extra keys, they may be ignored. If they miss keys, those cells will be left empty.
This tool is designed for flat data structures. If your JSON contains nested objects or arrays as values, they will be stringified (e.g., `"{...}"`) in the CSV output rather than expanded into new columns.
Since the conversion runs entirely in your browser's memory, you can handle fairly large files (up to several MBs). Extremely large datasets might slow down the browser but are not limited by server restrictions.
Yes! Once converted, you can click the "Copy" button to paste directly into Excel or Google Sheets, or copy the text to save it as a .csv file.
