formatdatetime error with if formula

Posted on by Community Power Pla...

Hi all,

 

I am trying to create a table with power automate flow but I face some issues when I run the testing.

There is the error reason:

Unable to process template language expressions in action '附加至字串變數_2' inputs at line '0' and column '0':

'In function 'formatDateTime', the value provided for date time string '44841' was not valid.

The datetime string must match ISO 8601 format.'

For column is empty, it shows successfully null in table.

But for the column with date information, it shows error instead.

 

Anyone how to fix this? Thanks a lot!

    Try changing the advanced options in your Excel action to return dates in ISO 8601 format.

    The output that you are getting is 44841 which is serial number format. So you could convert that by hand manually, but you should be getting ISO dates out. You can see this short video I did on it here:
