Hi All -
Is there any way to convert Datevalue ( like 44063) and string date (12/13/2020) into actual date mm/dd/yyyy.
You have two different formats in your data. I would probably separate them first, due to them being different datatypes as well.
Once separated, you can use a formula tool with a datetimeadd() function to convert the numbers to date, and a datetime tool to convert the word-formatted dates to dates. After that you can use a union to create one population.
