What type of files are primarily used in data processing for Workday?

XLSX files, which are Excel spreadsheet files, are primarily used in data processing for Workday due to their structured format that allows for efficient organization of data. Workday’s data loading process often relies on spreadsheets as they can accommodate large amounts of data and facilitate bulk uploads. The structured nature of XLSX files allows for columns representing various fields such as employee information, financial data, and other critical data points that Workday needs to process effectively.

Additionally, XLSX files support data validation and can include formulas, making them ideal for preparing data before loading it into the Workday system. Their compatibility with various data manipulation tools further enhances their utility in data processing for Workday implementations. Other file types, such as PDF files, images, or Word documents, do not provide the same level of structure or compatibility for data loading and processing tasks, which limits their use in this context.
