## What it is
Tidy Viewer (tv) is a cross-platform CLI pretty printer for tabular data that formats CSV, TSV, PSV, Parquet, and Feather files with column styling, colors, and significant-digit formatting. It streams large files memory-efficiently and is configurable via a dotfile.

## Use cases
- pretty print a csv file in the terminal
- view large csv files without loading them into memory
- preview parquet files from the command line
- display tabular data with aligned columns and colors
- replace cat for csv files with a readable viewer
- quickly inspect row and column counts of a dataset

## When to choose
- you need fast, readable terminal output for CSV/TSV/Parquet data
- you work with large files that need streaming
- you want a lightweight alternative to opening data in a spreadsheet or notebook

## When to avoid
- you need interactive scrolling, filtering, or editing of data
- you need a GUI data viewer
- you need to transform or write data, not just display it
