Required Fields & Validation
Conditional, formula-based required-field validation that blocks bad data.
The problem
monday will happily let a critical item move forward with the status blank, the owner unset, or the budget empty. Simple required-field checks help, but real rules are conditional — require a close date only when the deal is Won, or a mitigation only when risk is High. Without that depth, bad data still lands.
How it works
Write a rule
Define what's required and when — plain required fields, or conditional and formula-based rules that only apply in the states that actually matter.
Guard the transition
When someone tries to move or update an item that doesn't satisfy the rule, the change is blocked with a clear message telling them exactly what's missing.
Keep boards clean
Bad data never lands, so the reports, automations, and dashboards downstream stay trustworthy — across a single board or many.

FAQ
What kinds of rules can it enforce?
Beyond plain required fields, Field Guard does conditional and formula-based rules — required only when another column has a certain value — and it works across boards.
Does it block or just warn?
It blocks the invalid transition until the required data is filled in, so bad items can't slip through; the message says exactly what's needed.
What's on the free tier?
One rule free on up to 10 seats. Pro unlocks unlimited rules plus conditional and formula logic.
