What is the difference between CSV and JSON formats?

CSV (Comma-Separated Values) is a simple text format for tabular data, while JSON (JavaScript Object Notation) is a structured data format that represents data as key-value pairs and arrays, making it easier for programming languages to process.

Does the converter handle complex CSV files?

Yes, the converter handles quoted values, escaped commas, and standard CSV formatting. For very complex CSV files with multi-line values or special characters, consider using a more advanced CSV parser.

Is my CSV data processed securely?

Yes, all conversion happens locally in your browser. Your CSV data never leaves your device, ensuring complete privacy and security for sensitive data files.

Can I convert large CSV files?

The tool works with reasonably sized CSV files. For very large files (over 10MB), you may experience browser performance limitations. Consider splitting large files or using server-side processing for big data.

What if my CSV doesn't have headers?

The converter assumes the first row contains headers. If your CSV doesn't have headers, the tool will still convert it, but the JSON objects will use generic keys. Consider adding headers for better data structure.

Can I customize the JSON output format?

The tool generates standard JSON format with 2-space indentation for readability. The output is optimized for both human reading and programmatic use in applications and APIs.
