About:
csvlens is an interactive command-line CSV viewer designed for exploring large datasets efficiently. It provides a spreadsheet-like interface directly in the terminal, allowing users to navigate, filter, and analyze data without loading the entire file into memory. The tool focuses on speed and usability, making it ideal for quick data inspection.
Key Features:
  • Lazy loading for handling large files
  • Interactive filtering and column selection
  • Column statistics (min, max, mean, etc.)
  • Keyboard-driven navigation
Use Cases:
  • Quickly inspecting large CSV log files or exports
  • Analyzing data columns without writing scripts
  • Previewing datasets before processing
Alternatives:
  • visidata – VisiData is more powerful and feature-rich but has a steeper learning curve; csvlens is simpler and faster for basic viewing.
  • csvkit – csvkit provides CLI tools for manipulation but lacks an interactive viewer; csvlens fills the interactive exploration gap.
