# Laneboard Trello Import

> Turn a Trello board export (JSON) into a Laneboard board with lists, labels and checklists. Converts the JSON file Trello exports for a board into a Laneboard project file: lists, cards, labels, assignees, due dates, checklists, comments, link attachments, cover colours and the moves between lists. It shows what was mapped and what was left out.

Part of usefulweb.app (https://usefulweb.app/). Part of [Laneboard](https://laneboard.usefulweb.app/) (ownerApp: laneboard). Results are deterministic calculations from the inputs and the listed assumptions; the API returns exactly what the web page shows.

## Use it
- Human interface: https://laneboardtrelloimport.usefulweb.app/ (interactive tool at https://laneboardtrelloimport.usefulweb.app/tool)
- JSON API: POST https://laneboardtrelloimport.usefulweb.app/api/v1/calculate with a JSON object of inputs (schema: https://laneboardtrelloimport.usefulweb.app/api/v1/tool)
- OpenAPI: https://laneboardtrelloimport.usefulweb.app/openapi.json
- MCP (Streamable HTTP): https://laneboardtrelloimport.usefulweb.app/mcp - tool `laneboard_trello_import`

## Inputs
- trello (textarea): Trello export (JSON) - In Trello: board menu → Print, export and share → Export as JSON. Paste the file here or upload it below.
- trelloFile (file): Trello export file (optional) - Used instead of the pasted text when given.
- includeArchived (boolean): Keep archived lists and cards (as archived)
- includeComments (boolean): Keep comments

## Method
- Lists and cards are sorted by Trello’s position numbers. Closed lists and cards become archived ones (or are skipped). Board, list and card names, descriptions (Markdown), labels, members, checklists and items keep their text.
- Label colours map to Laneboard’s ten colours (“_light” and “_dark” shades to their base colour, black and colourless labels to grey); the board background colour maps to the nearest of eight backgrounds by hue.
- Due dates are converted to UTC date and time; “due complete” becomes done. Attachments become links when their URL starts with http(s); files uploaded to Trello stay on Trello. A card cover colour becomes the cover colour.
- Actions: comments (commentCard) become comments; createCard and updateCard with listBefore/listAfter rebuild each card’s history, which the statistics use for lead and cycle times. Without a createCard action the creation time is read from the card id (its first 8 hex digits are seconds since 1970).
- Custom fields, power-ups, stickers, votes, start dates and image covers are not imported; the warnings count them.

## Limits
- Trello is a trademark of Atlassian. Laneboard reads the export file you provide; it does not connect to Trello.
