Bulk Create Subitems in monday.com: 4 Methods Compared (2026)

Direct answer: monday.com can bulk-create subitems natively in two ways: automation recipes that create predefined subitems (one or several, chained) when a trigger fires, and Excel import, which lands rows as items you then convert by hand. For adding dozens of subitems across many existing items on demand, with values inherited from each parent, you need an app. SubItems Pro’s Create tab does up to 50 per item.

Method 1: Add subitems by hand

The baseline: expand an item, click + Add subitem, type. When subitems are similar, selecting an existing subitem and duplicating it from the menu at the bottom of the screen beats re-typing.

The limit is arithmetic. Five subitems on forty items is 200 rows of typing. Manual is right when the numbers are small and wrong the moment they aren’t.

Method 2: Native automation recipes (best for new items)

monday.com’s automation center can create subitems when a trigger fires. Per monday.com’s support docs:

• The recipe “When status changes to something, then create a subitem” exists out of the box.
• The action chains for multiples: “When an item is created, then create a subitem, and then create a subitem, and then create a subitem.”
• You can map parent item fields onto the new subitem’s columns, so automation-created subitems arrive pre-filled with parent data.

Where it stops:

• The subitem set is hard-coded in the recipe: changing your standard checklist means editing the automation.
• Recipes fire when the trigger happens. They don’t backfill the 300 items already sitting on your board.
• Different subitem sets for different situations means one recipe per variation, and each creation consumes your monday.com plan’s automation actions.

For standing checklists on incoming items, this is the right tool and it costs nothing extra. More patterns in monday.com subitem templates.

Method 3: Excel/CSV import

If your subitems already live in a spreadsheet, import looks like the obvious bulk route. The catch, stated plainly in monday.com’s import docs: subitems from Excel are imported as items onto your board, after which you convert them to subitems manually.

The native importer (.xlsx, .xls, .csv — first tab only, up to 8,000 rows) gets data into monday.com quickly, but every row arrives as an item. Reparenting hundreds of rows under the right items remains a by-hand exercise. Third-party importer apps on the marketplace can map rows directly to subitems if imports are a recurring part of your workflow.

Where it stops: the native path gets your data into monday.com, but you still don’t have subitems. Reasonable for one-time migrations where the conversion step is acceptable.

Method 4: SubItems Pro’s Create tab (existing items, on demand)

SubItems Pro adds a board view for bulk subitem operations. Its Create tab targets the exact gap the native methods leave: adding subitems to many existing items at once, right now, no trigger required.

1. On the board, multi-select the items that should receive subitems: anything from a couple of items to the whole board.
2. Open the SubItems Pro view → Create tab.
3. Set how many subitems to add and name them. The cap is 50 per selected item per operation, across any number of selected items.
4. Optionally enable inheritance from each parent: Copy All or Manual (pick specific columns). 18 column types can be inherited: Status, Person, Date, Timeline, Numbers, Link, Email, Checkbox, Phone, Country, Location, Tags, Rating, World Clock, Week, Text, Long Text, and Hour.
5. Run. Every selected item gets the set, and each subitem inherits values from its own parent.

If the subitem board is missing a column being inherited, SubItems Pro creates it automatically, in parent-board order; inherited Status columns arrive with the parent’s labels and colors. No column prep needed.

What it costs: one action per subitem created; inheritance itself is free. The free plan includes 20 actions per month, and paid plans are flat ($8–$118/mo) with no per-seat pricing. Full mechanics in the user guide.

To push parent values into subitems that already exist, that’s a bulk edit, not a create. See copying parent column values to subitems.

How do the four methods compare?

	Manual	Automation recipe	Excel import	SubItems Pro Create
Works on existing items	Yes, one at a time	Only when a trigger fires	Rows arrive as items; convert by hand	Yes — any selection, on demand
Many items in one pass	No	One item per trigger event	No — reparenting is per-item	Yes
Subitems per run	Whatever you type	Fixed set in the recipe	Up to 8,000 rows per file	Up to 50 per selected item
Parent values inherited	Typed by hand	Yes — mapped at creation	From the sheet, not the parent	Yes — 18 column types
Cost	Free	Uses plan automation actions	Free (native importer)	1 app action per subitem; free tier 20/mo

Which method should you use?

Start native. Manual is fine under ten subitems total. Automation recipes are the right call for standard checklists on every new item, and import fits spreadsheet migrations if you can live with the conversion step. The app enters when you need subitems on many existing items at once (backfilling a checklist onto a live board, spinning up deliverables across a whole campaign group) or when inheriting parent values matters. And if the subitems you need already exist on another item, copying beats creating: see how to copy subitems to another item.
