I've tried various forums for answers to this issue but none have succeeded. I have an extensive spreadsheet that I want to import a Sharepoint list. The issue is the date column. irrespective of how I format the date in Excel it does not conform to the date/time format in Sharepoint.
The error message (note the error varies depending on how I format in excel)
I am sure there should be a simple function fix but I suspect I don't have sufficient knowledge to understand potential solutions offered on other forums.
any help/advice gratefully received.

Note the example shown is a test file I'm using as the working sheet is too large to easily manipulate

@TSimsD Excel stores dates as an integer of the number of days since 30 December 1899. So you need to convert that integer to a date before your flow can use the output in SharePoint.
So you will need to add Compose control.
The table in my spreadsheet has a column called Time:
In your flow you'll need to convert that column using an expression in a Compose control:
formatDateTime(addDays('1900-01-01', add(int(items('Apply_to_each')?['Time']),-2)), 'yyyy-MM-dd')
(the way I do it is to use 1900-01-01 for ease of remembering rather than 1899-12-30, then take off 2 days from the result)
You then use the output of that Compose in the relevant field in your SharePoint Create item action.

I have the same scenario as your solution and have tried your expression in my workflow. However, I am getting an error:
"Unable to process template language expressions in action 'ComposeFormatExcelDate' inputs at line '1' and column '9734': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'."
Can you assist?

@sumitarjandas I am getting the same error and really need some help sorting it out. I’ve tried it all!

I agree with the approach that @RobElliott provided.
I've done this before but using a variable (vs compose) to convert and store the Excel date. More details here: Import Excel data into an existing SharePoint List using Power Automate – Norm Young
I hope this helps.
