About this Tool

This advanced CSV Viewer is a client-side tool that helps you inspect, sort, and manipulate CSV data with high performance. All processing happens in your browser - no data is sent to any server.

  • Parse and preview CSV data with advanced table functionality
  • Click column headers to sort data (ascending/descending)
  • Automatic virtualization for large datasets (100+ rows) for optimal performance
  • Robust CSV parsing that handles quotes, escapes, and malformed data
  • Support for custom delimiters (comma, tab, semicolon, etc.)
  • Upload CSV files or paste data directly
  • Export to CSV or JSON format
  • Real-time parsing error detection and reporting
  • No data leaves your browser - completely private

Usage Tips

  • • For tab-separated files (TSV), use "\t" as the delimiter
  • • The first row is automatically used as column headers
  • • Empty rows are automatically filtered out
  • • Click any column header to sort the data by that column
  • • Large datasets (100+ rows) are automatically virtualized for smooth scrolling
  • • Parsing errors are shown but won't prevent data display
  • • Export to JSON to convert CSV data into a structured format
