Using Fromula to move rows

[Kello]

Hello,
I am stuck on an issue and looking for some help. I am using excel to track task from "Date started" to "Date completed" as well as other data needed about each task. Each month of the year having its own sheet. I am trying to find a way to flag task that have a start date but no complete date across the whole year and list each tasks information on a different sheet , like a "to be don list".
Is this possible?

Hi and welcome

do you absolutely need one sheet per month?

The easiest way is to concentrate all on one sheet from which monthly data can be extracted.

Could you consider doing this?
