What is a JSON to CSV Converter?
A JSON to CSV Converter is a tool that transforms JSON (JavaScript Object Notation) arrays into clean, structured CSV (Comma-Separated Values) format. JSON is a popular data format used in APIs, web applications, and data storage — while CSV is a universal format used in spreadsheets, databases, and data analysis tools like Excel, Google Sheets, or Python's pandas.
What is JSON?
JSON is a lightweight data-interchange format that uses key-value pairs to represent structured data. It's commonly used in web APIs, server responses, and config files. Here's a simple JSON example:
[
{ "name": "Alice", "age": 25 },
{ "name": "Bob", "age": 30 }
]
What is CSV?
CSV stands for Comma-Separated Values — a plain text format where each line represents a row of data and values are separated by commas. It's widely supported by spreadsheet software, making it a go-to format for importing and exporting tabular data.
Why Convert JSON to CSV?
- Easy spreadsheet import: Convert JSON data for Excel, Google Sheets, or Numbers.
- Better readability: View your data in tabular form rather than nested structures.
- Interoperability: CSV is accepted by most data tools, databases, and BI software.
- Data analysis: CSV simplifies sorting, filtering, and visualization.
How This Tool Works
- Paste your JSON array into the input box. It should be an array of objects like
[{"name":"Alice"}, {"name":"Bob"}].
- Click the Convert to CSV button.
- The tool extracts the keys from the JSON objects and generates a properly formatted CSV string.
- You can then copy or download the CSV output directly from the browser.
Supported JSON Structures
- Flat arrays of objects
- Mixed value types (numbers, strings, booleans)
- Nested structures are flattened using dot notation (e.g.,
user.name)
Example
JSON Input:
[
{ "name": "Alice", "age": 25 },
{ "name": "Bob", "age": 30 }
]
CSV Output:
name,age
Alice,25
Bob,30
