Overview

Data Set is a work surface designed for managing up to 10 million items in a single table. Where a standard board supports up to 100,000 items for the Enterprise plans, a Data Set is built for teams that need a single source of truth at a large scale, such as leads, contacts, tickets, and timesheets, without splitting data across multiple boards.

Use this guide to understand how a Data Set differs from a standard board, what it supports, and how to get started.

When to use a Data Set vs. a board

A Data Set is the right choice when some or all of the following apply to your use case:

You need one central table as the single source of truth, with no data split across boards
You are working at a scale that a standard board cannot support, or you are migrating a high-volume workflow into monday.com
All of your teams, AI agents, and workflows require access to the same records with the same structure
You have a large volume of records created every day, week, or month, and managing deletion or archiving becomes a hassle

In other scenarios, standard boards may be a better fit. If different teams, regions, or departments manage separate lists of the same entity type, each team may be better served by its own board, without the limitations Data Set enforces.

Note: Hierarchical use cases such as accounts with nested contacts are not suited to Data Set at this time, as subitems are not supported. A standard board or multiple linked boards may be more appropriate for these workflows.

How to create a Data Set

Creating a Data Set follows the same logic as creating a standard board. You create the Data Set, add your columns, and then populate it with data. You can add items manually from the table, import a file directly from the UI, use WorkForms, or let automations, integrations, and AI agents create items for you. For large-scale migrations from external systems or existing boards, the batch import API supports up to 20,000 items at a time.

Note: Only account admins can create a Data Set.

1Click the + in the left navigation panel, hover on board, and click on New Data Set. This creates an empty Data Set.

2Add your columns directly in the table, the same way you would on a standard board.

3Populate your Data Set. You can add items directly from the table, import a file, use a form, or create records via integrations, automations, or AI agents. For large-scale migrations, use the batch import API, which supports up to 20,000 items at a time.

Common use cases

Data Set is designed for large-scale, active record management where all items must live in a single table. Common use cases include:

Timesheet tracking
Leads and contacts
Service requestors and tickets
Resource directories (employees, contractors, assets)
Inventory and product catalog management
AI data enrichment workflows and agentic flows
Migrating high-volume data from external systems into monday.com
Creating a snapshot of a large data set to be used as a report

What Data Set supports

FAQs

How is a Data Set different from a board?

A Data Set behaves like a board, but supports up to 10 million items in a single table. To support that scale, some board features such as subitems, groups, and drag-and-drop reordering are not available.

Who can create a Data Set?

Data Set is available on the Enterprise plan across all products. Only admins can create a Data Set.

Can I use automations and integrations with a Data Set?

Yes. Automations, API, MCP, and integrations are fully supported. AI columns, AI Agents, monday sidekick, and Vibe are also supported.

I can only see 20,000 items. How do I access the rest?

The table view displays the first 20,000 items at a time. Use sort and filter to surface any item across the full Data Set (up to 10 million items).

How do I populate a Data Set with items?

You can add items directly from the table, import a file from the UI, use a form, or create records via integrations, automations, or AI agents. For large-scale migrations, use the batch import API, which supports up to 20,000 items at a time.
