You have multiple spreadsheets that share the same columns. Which approach is suitable for creating a longer table with rows from each spreadsheet?
Normalization
Data append
Data merge
Data blending
Data append adds additional rows to an existing structure when columns are the same in each data set. Data merge pairs records based on a matching key, data blending combines columns from multiple data sources for combined analysis, and normalization modifies the structure of data rather than focusing on adding additional rows.
