A CLI tool for managing Trello boards via the Trello REST API.

Setup

1. Get your Trello credentials

• API Key: Go to trello.com/power-ups/admin, create a Power-Up, and copy the API key.
• Token: From the same page, generate a token with read/write access to your boards.

2. Set environment variables

Copy .env.example to .env and fill in your credentials:

cp .env.example .env

TRELLO_API_KEY=your_trello_api_key_here
TRELLO_TOKEN=your_trello_oauth_token_here

Alternatively, export them in your shell:

export TRELLO_API_KEY=your_api_key
export TRELLO_TOKEN=your_token

Commands

create board

Create a new Trello board.

trelctl create board "My Board"

Output:

Created board: "My Board" (id: abc123)

import lists

Create lists in a board from a CSV file.

trelctl import lists --board "My Board" lists.csv
trelctl import lists --board "My Board" --dry-run lists.csv

CSV format:

Column	Required	Example
name	Yes	Backlog

Example lists.csv:

name
Backlog
In Progress
Done

--dry-run validates the file and resolves the board without creating anything.

import cards

Create cards in a board list from a CSV file.

trelctl import cards --board "My Board" --list "Backlog" cards.csv
trelctl import cards --board "My Board" --list "Backlog" --dry-run cards.csv

CSV format:

Column	Required	Format	Example
name	Yes	Plain text	Fix login bug
description	No	Plain text	Steps to reproduce...
labels	No	Comma-separated label names	Bug,High Priority
due_date	No	YYYY-MM-DD	2026-04-15
checklist	No	Pipe-separated items	Write tests|Review PR|Deploy
members	No	Pipe-separated member IDs	abc123def456|ghi789jkl0

• Labels must already exist on the board. Unknown label names are skipped with a warning.
• members values must be Trello member IDs (alphanumeric), not usernames or email addresses.
• Column order does not matter. name is the only required column.

Example cards.csv:

name,description,labels,due_date,checklist,members
Fix login bug,Reproduce on mobile,Bug,2026-04-15,Write test|Fix bug|Deploy,
Add dark mode,,Enhancement,,,,

--dry-run validates the file, resolves the board, list, and labels, but creates nothing.

get lists

Export all lists from a board to CSV.

trelctl get lists --board "My Board"
trelctl get lists --board "My Board" > lists.csv

Output columns: name

get cards

Export all cards from a board (or a specific list) to CSV.

trelctl get cards --board "My Board"
trelctl get cards --board "My Board" --list "Backlog"
trelctl get cards --board "My Board" > cards.csv

Output columns: name, description, labels, due_date, checklist, members

The output uses the same format as import cards, so exported files can be re-imported.

get members

Export all members of a board to CSV.

trelctl get members --board "My Board"
trelctl get members --board "My Board" > members.csv

Output columns: name (Trello member IDs)

Board and list resolution

All --board and --list options accept either a name or an ID:

• Name: matched case-insensitively against your boards/lists.
• ID: used directly if no name match is found.

If neither matches, the command exits with an error.

Round-tripping

get cards output is compatible with import cards input, which allows you to export cards from one board and import them into another:

trelctl get cards --board "Source Board" > cards.csv
trelctl import cards --board "Target Board" --list "Backlog" cards.csv
