Function Details

This function unpivots data from a wide format to a tall format, making it easier to analyze and work with in databases, visualizations, or other applications. It takes a single column of data (dimension), column headers, and a range of data values, and returns a table with the dimension, column headers, and corresponding data values in separate rows. To use this function, define dimension as the column containing the dimension data (such as names or categories), column_headers as the column containing the pivoted headers (e.g., dates or subcategories), and data_range as the matrix containing the data to be unpivoted. Place this function in the first cell where you want the new unpivoted data to appear, and it will automatically reformat the specified range into an expanded format. This function produces an array of values outside of the cell containing this formula.

What is a Named Function in Google Sheets?

Named functions enable the creation of custom, reusable formulas that mimic built-in functions, streamlining calculations and data manipulations. These functions simplify complex formulas, making spreadsheets more readable and less prone to errors. By encapsulating intricate logic within a single function call, they enhance consistency across your data. Utilizing named functions reduces the need to write lengthy formulas repeatedly, thereby improving workflow efficiency and productivity in data analysis and management.
