Above are the date data I obtained from an Excel file, I am not supposed to format cell nor hardcode the data but it will show null for those in such format: 7/2/2023. But if I tick the "First row contains data", my header will become one of the data and I still have no clue how to convert them into a uniformed format.

Hi @imivan ,

You can apply the date function for each pattern as below.

I hope this helps.

Workflow

Date Functions in Formulat tool

Output = 

IF REGEX_Match([Data], "\d+")
THEN ToDate(ToNumber([Data]))
ELSEIF REGEX_Match([Data], "\d+\/\d+\/\d{4}")
THEN DateTimeParse([Data],"%d/%m/%Y")
ELSE Null()
ENDIF

Output

I manage to solve it after some brainstorming, yours is definitely smarter and easier, thanks
