Adding Excel Dates from Sharepoint Lists using Power Automate

(0) ShareShare
ReportReport
Posted on by MelB10 18

Hi There. 

 

I have a Flow that Updates a Sharepoint List from an Excel file with a Condition in. (If the item already exists, update item, if not, create item).

I have tried to add dates in and my date columns in Excel are 'Start Date' and 'End Date' but I keep getting the same error, and I have read and watched numerous resources. 

 

Error message: 

InvalidTemplate. Unable to process template language expressions in action 'Update_item' inputs at line '0' and column '0': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'.

 

Expressions I'm  using: 

addDays('1899-12-30',int(items('Apply_to_each')?['Start Date']),'yyyy-MM-dd')
addDays('1899-12-30',int(items('Apply_to_each')?['End Date']),'yyyy-MM-dd')

 

Here is my Flow:

Appreciate your help.

    Hi @MelB10 

     

    Set the date format to ISO8601 in the List row present in a table so that you don't have to use the addDays function.

    After setting the format, just use the formatDateTime function to convert it to the 'yyyy-MM-dd' format.
