I need to be able to add tasks (within a checklist on a specific card) and assign them to someone with a due date. I want to be able to perform this action from a third-party application (such as Google Sheets or another tool) without having to open the Trello card, enter the task name manually, then click again to assign a person and once more to set the due date. That process is too time-consuming.
At the same time, I need an overview of the subtasks belonging to ongoing checklists, broken down by person. I need to make sure I don't miss overdue tasks, so the calendar view is not sufficient.
Hi Violaine,
For the overview/reporting part, I’d try Cross-Board Reporting & Dashboards: https://trello.com/power-ups/66291013ec3abfbf13b255c6
It can show checklist-related data in a table/dashboard view, including checklist summaries, card links, overdue checklist items, and filters by conditions such as overdue items. That should help with the “overview by person / don’t miss overdue tasks” part.
For creating checklist items from Google Sheets or another external tool, you would likely need an automation tool such as Make, Zapier, Power Automate, or a direct Trello API setup. Trello’s API supports creating checklist items with fields like name, due, and idMember, so assigning a person and due date from an external source should be possible with the right setup. Official API reference: https://developer.atlassian.com/cloud/trello/rest/api-group-checklists/
Trello’s own advanced checklist docs are here: https://support.atlassian.com/trello/docs/how-to-use-advanced-checklists-to-set-due-dates/
Hi @Violaine Barroux ,
Trello's built-in checklists don't support bulk input from external tools or a consolidated subtask overview by person. However, some tools can help with both.
No-code automation tools like Zapier or Make can connect Google Sheets to Trello. You can set up a workflow so that adding a row in your sheet automatically creates a checklist item on a specific card, with the assignee and due date filled in.
If you want more control, you can use the Trello API with a simple Google Apps Script to push rows from Google Sheets directly into Trello checklists.
The native Trello calendar and dashboard views don't provide a consolidated checklist-item view across cards.
You can consider using some power-ups like Placker or Bridge24, which allow you to manage all checklist items across multiple cards and boards in one view.
Hope it helps 🙌
Liam
