Converting JSON to CSV

JSON (JavaScript Object Notation) is the dominant format for APIs, configuration files, and data interchange on the web. CSV (Comma-Separated Values) is the universal spreadsheet format understood by Excel, Google Sheets, database import tools, and virtually every data processing application. Converting between these two formats is one of the most common tasks in data management.

When to Convert JSON to CSV

You might need this conversion when exporting API data for analysis in a spreadsheet, preparing data for a database import that requires CSV format, or sharing structured data with colleagues who prefer tabular formats. Our converter handles the transformation entirely in your browser, so your data stays private. If you need to validate your JSON before converting, try our JSON formatter first.

How the Conversion Works

The tool collects all unique keys from every object in your JSON array to form the CSV header row. Each object becomes one CSV row, with values placed in the column matching their key. Values containing the delimiter, double quotes, or newlines are automatically quoted per RFC 4180. Missing values result in empty cells. For counting characters in your output, use the character counter.

Frequently Asked Questions

What JSON format does this tool accept?

This tool accepts a JSON array of objects, where each object represents a row. For example: [{"name":"Alice","age":30},{"name":"Bob","age":25}]. All objects should have the same keys for best results.

Can I change the CSV delimiter?

Yes. You can choose between comma, tab, or semicolon as the delimiter. Comma is the standard for most applications, tab works well for pasting into spreadsheets, and semicolon is common in European locales.

How are special characters handled?

Values containing the delimiter character, double quotes, or newlines are automatically wrapped in double quotes. Any double quotes within values are escaped by doubling them, following the RFC 4180 CSV specification.

Is my data sent to a server?

No. All conversion happens entirely in your browser using JavaScript. Your JSON data never leaves your device. The download file is generated client-side using Blob URLs.
