JSON to CSV Converter

What is JSON to CSV Converter?

JSON to CSV Converter is a powerful online tool that transforms JSON (JavaScript Object Notation) data into CSV (Comma-Separated Values) or TSV (Tab-Separated Values) format. This converter is essential for data analysts, developers, and anyone who needs to convert structured JSON data into spreadsheet-compatible formats for analysis, reporting, or data migration purposes.

The tool intelligently handles complex JSON structures by flattening nested objects and arrays, making it easy to work with hierarchical data in tabular format. Whether you're working with API responses, configuration files, or database exports, this converter streamlines the process of making JSON data accessible in Excel, Google Sheets, or other spreadsheet applications.

With support for both comma and tab separators, the converter provides flexibility for different use cases and ensures compatibility with various data processing tools and platforms.

Key Features:

• Smart JSON Parsing: Handles arrays of objects, single objects, and complex nested structures
• Object Flattening: Automatically flattens nested objects using dot notation (e.g., "user.address.city")
• Array Handling: Converts arrays to JSON strings for preservation in CSV format
• Multiple Separators: Choose between comma (CSV) and tab (TSV) delimiters
• File Upload Support: Import JSON files directly for conversion
• Real-time Conversion: Instant conversion as you type or modify settings
• CSV Field Escaping: Proper handling of special characters, quotes, and line breaks
• Download & Copy: Export results as .csv or .tsv files or copy to clipboard
• Error Handling: Clear error messages for invalid JSON with syntax highlighting
• Data Persistence: Automatically saves your work with 12-hour expiry
