How could I automate a tracking list of "how many projects users were on at given dates"

Hi PierrickE,

Thanks for reaching out and apologies for the delayed response! I think an Office Script might be able to help you out; to double-check, do you have access to the Office Scripts feature? You can confirm this by seeing if you have the Automate tab in Excel on the web.

If you can use Office Scripts - before I give specific suggestions, could you clarify what you mean when you mentioned that dates are going to move?

Best,

Michelle
