How can dates be standardized effectively in data preparation?

Standardizing dates effectively in data preparation is crucial for maintaining consistency and ensuring accurate analysis. The choice of using the Original Formats box in a dates transformation is a practical approach because it allows you to specify how the data should be interpreted based on its original format. This feature makes it easier to handle various date formats that might be present in the dataset, which could include different locales, formats like MM/DD/YYYY or DD/MM/YYYY, and other potential variations.

By utilizing the Original Formats box, you ensure that dates are transformed correctly based on their intended representation without inadvertently misinterpreting them. This method automates much of the standardization process, reducing the risk of error and saving time compared to manual tweaks or reliance on external tools. It fosters a systematic way to process and convert diverse date inputs into a uniform format suitable for analysis.

In contrast, formatting dates in Excel prior to import limits flexibility, as it may not accommodate all date formats encountered later. Creating a new date column manually is time-consuming and prone to human error, especially with large datasets. Relying solely on default date formats in the system can lead to misinterpretations if the incoming data does not match those defaults, highlighting the importance of actively specifying the original formats. This is why the
