How to standardize date format in Power Query?

[mrbuttons07]

Hello everyone,

I have a dataset that looks like this. The date format is not standardized on all columns.

When I tried to change the data type in power query, it triggers an error.

How can I standardize the format of the date columns in power query?

NewStep=Table.TransformColumns(PreviousStepName,{"Id",each _},each Date.From(Text.Combine(Text.SplitAny(Text.From(_),"-/"),"-")))
