Unlike standard functions that handle one cell at a time, this dynamic calculation method allows for complex data transformations without cluttering your workspace with helper columns. An array formula in Google Sheets operates on one or more arrays, processing multiple cells simultaneously to return a single result or a transformed array.

Performance is another consideration when applying logic to very large datasets. While Google Sheets still recognizes this syntax for backward compatibility, modern versions often handle the logic automatically with the `ARRAYFORMULA` function.
To resolve this, ensure that the arrays being processed have the same number of rows or columns. It eliminates the need to copy the formula down manually, ensuring consistency from the header row to the end of the data stream.
