The datetime string must match ISO 8601 format

I have a column with date and time in excel and there are empty values. I need to export the table into the Sharepoint list. I used an expression: 

if(empty(items('Apply_to_each')?['Date']), null, formatDateTime(item()?['Date'], 'yyyy-MM-dd HH:mm tt'))

but got an error. How can I solve this?

    The string will need to look like this.

    2022-01-13T00:00:00.0000000

     

    So, you're almost there. Just concatenate the individual parts to conform with that example.

    Hi, thank you for the reply. Could you help me with expression? I know expression for dd/mm/yyyy: 

    concat(split(item()?['Date'],'/')[2],'/',split(item()?['Date'],'/')[1],'/',split(item()?['Date'],'/')[0])

    but I don't understand how to make formula for date with time. Thank you in advance

    Hi @SM_11 

     

    You can try this formula:

    if(empty(items('Apply_to_each')?['Date']),null,formatDateTime(concat(split(items('Apply_to_each')?['Date'],'/')[1],'/',split(items('Apply_to_each')?['Date'],'/')[0],'/',split(items('Apply_to_each')?['Date'],'/')[2]),'yyyy-MM-dd HH:mm'))

     

    Best Regards,

    Levi
