How It Works

Features
  • Array of Objects: Convert standard JSON arrays into CSV rows with automatic header extraction
  • Nested Flattening: Flatten nested objects using dot notation (e.g., address.city) or stringify them
  • Multiple Delimiters: Output as comma, semicolon, tab, or pipe separated values
  • Smart Quoting: Automatically quotes fields containing delimiters, quotes, or newlines
  • All Keys Collected: Scans all objects to build a complete set of columns, even if some rows have missing fields
  • Single Object Support: Automatically wraps a single JSON object into an array for conversion
Common Use Cases

  • Export JSON database records for analysis
