How do you standardize the date format in Power Query for data coming from different sources?
Asked in the Technical Round stage. Testing Power Query data transformation knowledge.
Explain the transformation steps you would use when sources contain formats such as MM/DD/YYYY, DD/MM/YYYY, ISO timestamps, and locale-specific values. Include how you would handle invalid or ambiguous dates and verify that the standardized field is suitable for KPI reporting.
