try using the formula tool with DateTimeFormat([DateTime_Out],"%Y-%m-%d")
Here's some more info too https://help.alteryx.com/current/en/designer/functions/conversion-functions.html#idm45934712704128
Hey @Isha_Gupta, when using the DateTime tool, the month specifier is MM rather than mm and so you should be using ddMMyyyy instead. More info on this page: https://help.alteryx.com/2018.3/DateTime.htm?Highlight=date%20time
hey @Isha_Gupta remove the datetimetool and give this formula a go it should do the trick just create a new filed and set it to Date type
DateTimeParse([Input],"%d%m%Y")
