JSON to CSV Converter

Convert JSON arrays to CSV format for spreadsheets. Works with arrays of objects. Free, client-side.

About this tool

Convert a JSON array of objects into CSV (comma-separated values) format, ready to open in Excel, Google Sheets, or any spreadsheet application. The converter automatically extracts all unique keys as column headers and handles nested values, null values, and special characters that need CSV escaping. This is the fastest way to get JSON API data into a spreadsheet for analysis.

FAQ

What JSON structure does this expect?

An array of objects: [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]. Each object becomes a CSV row, and all unique keys become column headers.

How are nested objects handled?

Nested objects and arrays are converted to their JSON string representation in the CSV cell. For deeply nested data, consider flattening the JSON first.
