About This Tool

The JSON to CSV Converter transforms JSON array data into standard CSV (Comma-Separated Values) format, making it easy to import data into spreadsheets, databases, or data analysis tools like Excel and Google Sheets. Converting JSON to CSV is one of the most common data transformation tasks in data analytics, business intelligence, and reporting workflows. Analysts frequently need to convert API responses into spreadsheet-friendly formats for further analysis, visualization, and sharing with stakeholders who prefer working in Excel. This tool automatically detects all keys from your JSON objects, handles nested objects by flattening them with dot notation, and supports multiple delimiter options. Whether you are working with API responses, configuration files, or exported datasets, this converter provides a fast and reliable way to restructure your data.

How to Use

  1. Paste your JSON array into the input area. The tool accepts standard JSON format like [{"name": "John", "age": 30}, {"name": "Jane", "age": 25}].
  2. Choose your preferred delimiter — comma, semicolon, or tab — or let the tool auto-detect the best option.
  3. Click the "Convert" button to transform your JSON data into CSV format.
  4. Review the generated CSV output in the result area. The first row contains column headers extracted from your JSON keys.
  5. Use the Copy button to copy the CSV to your clipboard, or click Download to save it as a .csv file directly.

Frequently Asked Questions

Nested objects are automatically flattened using dot notation. For example, {"address": {"city": "NYC"}} becomes a column header "address.city" with the value "NYC". Arrays within objects are converted to JSON strings.
The tool is designed for JSON arrays. If you paste a single object like {"name": "John"}, it will be automatically wrapped in an array for conversion. For best results, ensure your data is in array format.
The tool collects all unique keys across all objects in the array. If an object is missing a particular key, the corresponding CSV cell will be left empty. This ensures all rows have the same number of columns.
No. All conversion happens entirely in your browser. Your JSON data is never transmitted to any external server, ensuring your data remains private and secure.
