data-preview.nvim

A simple Neovim plugin for data engineers and anyone who works with Parquet (and Avro soon). This plugin provides a "quick look" command to instantly preview the contents or metadata of large data files in a floating window, right from your editor.

Features

• Preview Data: Shows the first 20 rows of .parquet in a beautifully formatted table.
• Preview Stats: Shows file metadata for .parquet files (schema, row count, column stats) and .avro files (schema).
  • New Features: schema definition in PySpark styles
• Lightweight: Acts as a simple wrapper around external tools.
• Lazy-Loaded: Loads instantly only when you run one of its commands.

Dependencies

This plugin is a wrapper around external command-line tools. You must have them installed and available on your PATH.

• The recommended way to install this on most systems (especially modern Ubuntu) is with pipx:

pipx install parquet-tools
