Data validation is the process of ensuring that your data is accurate and clean. Validation rules—also known as check routines—are repetitive programming sequences that check for data accuracy, relevance, and security. The success of your efforts is dependent on how meticulous you are with implementing routines throughout the data lifecycle.
Data validation in Excel is possible, but limited due to the selection of available features. Their validation tool allows users to control what is entered into a cell by displaying a message, offering a drop-down menu, or preventing certain values. However, one of the major limitations of data validation in Excel is that a user can override the control by entering information in a non-validated cell and copying it into the controlled cell. This action can lead users to enter invalid information and can prevent the success of data validation.
Data validation is critical at every point of a data project’s life—from application development to file transfer to data wrangling—in order to ensure correctness. Without data validation from inception to iteration, crucial errors could translate into inaccurate forecasts, increased costs and lost revenue.
Validation is especially important to a data wrangler, who is often importing vast amounts of complex, unstructured, or semi-structured data from a myriad of disparate sources. The impact of improved data validation on the data wrangling process cannot be underestimated. Effective data validation efforts ensure that no oversight becomes a larger issue throughout the data lifecycle.
