How It Works
Paste your JSON data (array of objects) into the input field and the tool automatically converts it to CSV format. The tool detects all unique keys from your JSON objects and creates CSV headers. It handles nested objects by flattening them with dot notation. You can preview the CSV output, copy it to clipboard, or download it as a .csv file ready to open in Excel or Google Sheets. The conversion uses proper CSV formatting with quoted values and escaped commas. All processing happens in your browser.
Frequently Asked Questions
What JSON format is required?
The tool expects an array of objects. Each object represents a row, and object keys become CSV headers.
Can it handle nested JSON?
Yes! Nested objects are flattened using dot notation (e.g., user.name becomes a column).
Can I open the CSV in Excel?
Yes! The downloaded CSV file can be opened directly in Excel, Google Sheets, or any spreadsheet application.
What if my JSON has different keys?
The tool collects all unique keys from all objects and creates columns for each. Missing values are left empty.
Does it handle special characters?
Yes! The tool properly escapes commas, quotes, and newlines according to CSV standards.
