What Is
The CSV Viewer is an online tool that parses and displays comma-separated values (CSV) files in a clean, interactive table format. It goes beyond simple text display by automatically detecting column data types (numbers, dates, text), enabling column sorting with a click, providing text search and filtering, and supporting pagination for large files. The tool handles common CSV variations including different delimiters (comma, semicolon, tab, pipe), various quoting styles, and different line ending formats. It supports character encoding detection and conversion for international data. The viewer displays data in a responsive HTML table with options to show/hide columns, adjust column widths, and export filtered results. For large files, it implements virtual scrolling to maintain smooth performance even with thousands of rows.
How to Use
- Open the CSV Viewer tool in your web browser — no installation or account needed.
- Upload your CSV file using the file picker or paste CSV data directly into the text area.
- Configure parser options if needed — select delimiter character, encoding, and whether the first row contains headers.
- The tool will automatically parse and display your data in an interactive table format.
- Use column headers to sort data, and the search box to filter rows matching specific text.
- Export or copy the displayed data in your desired format.
Examples
Input: CSV: name,age,city Alice,30,NYC Bob,25,LA
Process: Parse rows by newline → Split by comma → Render as HTML table → Auto-detect headers
Result: Table with 3 columns (name, age, city) and 2 data rows
Input: TSV with tab delimiter: col1\tcol2\tcol3
Process: Detect tab delimiter → Parse columns → Format with proper spacing
Result: Correctly parsed 3-column table from TSV input
