How to convert date, if cell is empty

Hi @AaronMark ,

I would suggest you to go through the below Post :

In accordance with that, we would require to know whether there are different formats of date present in the data.

Once we identify the format/formats of date values we can use the solutions provided in the post to convert to DateTime.

We should be able to understand the cause better in that way.
