tblcopy

tblcopy reads CSV from stdin, converts it to a rich-text table, and copies the RTF table to the macOS clipboard. Useful for pasting into spreadsheets, or emails as tables.

Requirements

• Node.js 20 or newer
• macOS, with textutil and osascript available on PATH

Install

Install globally from npm:

npm install -g tblcopy

Or run without installing:

npx tblcopy < table.csv

Usage

cat table.csv | tblcopy

Add visible table borders with --border:

cat table.csv | tblcopy --border

Example:

printf 'Name,Amount\nCoffee,4.50\nRent,1200\n' | tblcopy

The first CSV row is rendered as table headers. Quoted CSV fields, escaped quotes, CRLF line endings, and embedded newlines are supported.

Development

npm install
npm test
npm start < table.csv
