FAQ

What is a CSV file?

CSV stands for Comma-Separated Values. It is a plain text format that stores tabular data, where each line represents a row and values are separated by commas. It is widely used for data exchange between applications.

How does this CSV viewer work?

Paste your CSV data and click 'View CSV'. The tool parses the first row as headers and converts each subsequent row into a JSON object, giving you a structured preview of your data.

Is my data safe?

Yes. All processing happens locally in your browser. Your CSV data is never uploaded to any server, ensuring complete privacy.

Can I use this for large CSV files?

This tool is designed for quick previews and moderate-sized data. For very large files, a dedicated desktop application may be more suitable.
