visibuffer.nvim

Open data files in VisiData inside a Neovim floating window.

Supports CSV, TSV, JSON, Parquet, SQLite, Excel, YAML, HDF5, PCAP, and more.

Requirements

• Neovim >= 0.9
• VisiData (pip install visidata)

Installation

lazy.nvim

{
  dir = "/path/to/visibuffer.nvim",
  config = true,
}

Usage

Opening a matching file (e.g. data.csv) automatically launches VisiData in a floating window.

Action	Key
Open VisiData for current file	<leader>Vd or :Visibuffer

VisiData opens in a terminal float. When you quit VisiData, the float closes and the file is ready to edit in Neovim. Running :Visibuffer again on the same file focuses the existing float.

Configuration

require("visibuffer").setup({
  auto_quit = true,
  args = {},
  filetypes = {
    "*.csv", "*.tsv",
    "*.json", "*.jsonl",
    "*.parquet", "*.feather", "*.arrow",
    "*.yaml", "*.yml",
    "*.xlsx", "*.xls",
    "*.sqlite", "*.sqlite3", "*.db",
    "*.h5", "*.hdf5",
    "*.pcap",
  },
  float = {
    width = 0.9,
    height = 0.9,
    border = "rounded",
    title = " VisiData ",
  },
})
