What is CSV Viewer?
Need to view and edit your CSV (Comma-Separated Values) files in a clean, interactive table? CSV Viewer takes your CSV data and displays it as an editable HTML table you can actually work with. Perfect for quick data analysis, editing, and filtering without opening Excel or other spreadsheet software.
CSV is one of the most common formats for data exchange, used everywhere from data exports to API responses. According to RFC 4180, CSV files are simple text files where each line represents a data record. Our viewer handles all standard CSV structures and makes them easy to work with.
The best part? Everything runs in your browser. Your data never touches our servers unless you explicitly share it. It's fast, free, and private.
