what it does

#	features	descriptions
	formats	A fast, keyboard-driven viewer and editor for CSV, TSV, JSON, JSONL, YAML, TOML, Markdown, Parquet, Arrow, Excel, SQLite and DuckDB.
	nested data	JSON, YAML and TOML open as a browsable tree and are edited in place.
	databases	SQLite and DuckDB tables are edited and saved as one transaction, with the SQL shown first.
	large files	Through the MCP server, large CSV, Parquet, Arrow and JSONL files are streamed, not loaded whole.
	analysis	Filter, sort, group, pivot, join, compute columns with expressions and window functions, describe, chart.
	mcp server	Started with `--mcp`, an AI assistant sends operations and reads back computed numbers instead of estimating them. `--mcp-write` lets it change database rows, always as a plan shown before it runs.

Cargo, Homebrew, AUR and APT install two commands: qrow and the short qrw.

Pre-built archives, with qrow alone: github.com/denisotree/qrow/releases

use with an ai assistant

claude code

claude mcp add -s user qrow -- qrow --mcp

json config Claude Desktop, Cursor, Zed…

{ "mcpServers": { "qrow": { "command": "/opt/homebrew/bin/qrow", "args": ["--mcp"] } } }

Use the full path: a desktop app does not start from your shell.

coming from tuitab

tuitab was renamed to qrow in 0.12.0.

cargo

cargo uninstall tuitab && cargo install qrow

homebrew automatic

brew update && brew upgrade

aur

Install qrow or qrow-bin; pacman offers to remove the old package.

apt

The old repository stays at 0.11.1. Remove it, then add the new one:

sudo rm /etc/apt/sources.list.d/tuitab.list /usr/share/keyrings/tuitab.gpg

mcp

claude mcp remove tuitab

Then add qrow as above, with --mcp-write if you had it. Permission rules follow the server's name: mcp__tuitab__tuitab_query → mcp__qrow__qrow_query, mcp__tuitab → mcp__qrow. In a JSON config, rename the key and the command to qrow.
