Create Outlook Calendar Event from Excel DateTime

(0) ShareShare
ReportReport
Posted on by
I am trying to create a PowerAutomate flow that periodically goes through an Excel sheet with a large list of dates for various steps of a project and creates corresponding events on an Outlook calendar. Initially, I followed this tutorial: Add Outlook Calendar Events in Excel Using Power Automate, but I'm having a lot of issues trying to get the date fields to work. 
 
This is the Excel sheet I'm working from, and it has Start/End Date columns that are set to a date format. Inputting those dynamic fields into the Start/End Time parameters for the "Create Event" action kept returning errors, so I tried creating another set of columns that formatted the dates as numbers so I could try using the addDays function. However, I am now receiving errors saying that those Start/EndDateNum columns are apparently containing strings, so it can't use that function. 
 
 
I tried looking into a lot of different options and formulas to get the date to work correctly, but I'm not having any luck. Below is the current formula in the Start/End time parameters that returned the above error.

    I assume that you are using the Excel List Rows in a Table action somewhere in your Flow.
    If the List row actions, click on "Show all" next to Advanced parameters.  The last parameter listed is DateTime format.  Set the format to ISO 8601.  This should allow you Excel dates to act like dates in your Flow.
