ℹ️ About JSON to CSV Converter
- JSON to CSV: Convert JSON arrays/objects to CSV format
- CSV to JSON: Convert CSV data back to JSON
- Nested Objects: Automatically flatten nested structures (user.name → user_name)
- Arrays: Arrays of simple values become comma-separated values in one cell; arrays of objects are kept as JSON text
- Custom Delimiters: Support for comma, semicolon, tab, and pipe
- Excel Compatible: The downloaded CSV is UTF-8 with BOM so accents display correctly in Excel; choose the semicolon delimiter for Excel with French/European regional settings
- Safe Typing (CSV → JSON): Only plain numbers and true/false are converted; values like 00123, +33612345678 or very long IDs stay text
⚠️ For complex nested structures, enable "Flatten Nested Objects" for best results.
