Date serial to date format
Hello, Im having an issue, i have a large dataset where the dates currently have the excel serial format. Is it possible to format this column to proper dateformat, perferably in the query? ...
In the Query Editor right click the Serial Date column header and Change Data Type to Date.
in Excel 1st date is 01-01-1900, so you could just add nr of days since then
e.g. use this code for new column#date(1900,1,1)+#duration([Serial Date]-2,0,0,0)
EDIT Sean's answer is way simpler, I'd go with it
In the Query Editor right click the Serial Date column header and Change Data Type to Date.
