Why Use an Online CSV Viewer?

CSV (Comma-Separated Values) files are one of the most common formats for storing and exchanging data. While spreadsheet applications like Excel can open CSV files, sometimes you need a quick, lightweight solution without opening heavy software. Our online CSV viewer is perfect for quick data inspection, making minor edits, or verifying file contents before importing into other systems. Since everything runs in your browser, your data stays completely private and secure.
