Code

JavaScript used in the Code step — already included in the template below.

Group by person · Code node

// Groups today's tasks by assignee. Adjust the property names to match your database.
const byPerson = {};

for (const { json: task } of $input.all()) {
  const who = task.property_assignee?.[0] || "Unassigned";
  (byPerson[who] ||= []).push(`• ${task.name}`);
}

const sections = Object.entries(byPerson).map(([who, tasks]) => `*${who}*\n${tasks.join("\n")}`);
if (!sections.length) return [];

return [{ json: { text: `📋 Due today:\n\n${sections.join("\n\n")}` } }];

Build it

Pick your tool — same automation, step by step.

Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder.
