## What it is
csvlens is a command-line CSV file viewer built in Rust, functioning like `less` but tailored for CSV files. It supports scrolling, regex search and filtering, sorting, column freezing, and piping CSV data directly into the viewer.

## Use cases
- view large csv files in the terminal
- search and filter csv rows with regex
- sort csv data by column from the command line
- pipe command output into a csv pager
- inspect delimited data files like tsv
- copy selected csv cells to clipboard

## When to choose
- you need a fast, interactive terminal viewer for CSV or TSV files
- you want to explore large CSVs without loading them into a spreadsheet
- you want to pipe CSV output from other commands into a pager

## When to avoid
- you need to edit or transform CSV data, not just view it
- you need a GUI spreadsheet experience
- you work with non-delimited structured formats like JSON or Parquet
