# JSON to CSV Converter Online — Free & Private | JSON Workbench

Convert JSON arrays to CSV files instantly. Handles nested objects, custom delimiters, and large files. Browser-based and private.

Convert large JSON datasets up to 100MB into spreadsheet-ready CSVs. Optimized for complex arrays and nested objects.

## How to Use
- **1. Paste JSON**: Paste your JSON array or object directly into the editor. We also support pulling data from the main JSON Workbench editor.
- **2. Flatten Data**: Our tool intelligently flattens nested objects using dot notation, ensuring all your data points are preserved in columns.
- **3. Download CSV**: Configure your delimiter (comma, tab, semicolon) and download the file for use in Excel, Google Sheets, or any database.

## The Smarter JSON to CSV Converter

Nested fields like address.city are automatically extracted into their own safe columns.
