A single value is returned by an aggregate function, which conducts a calculation on a set of values. Aggregate functions, with the exception of COUNT(*), ignore null values. The GROUP BY clause of the SELECT statement is frequently used with aggregate functions. There are no deterministic aggregate functions.
In Excel, lookup functions are used to search through a single column or row for a certain value from the same location in a second column or row. When there are numerous worksheets in a workbook or a big quantity of data in a worksheet, this happens frequently.
When you need to search in a single row or column and find a value from the same point in a second row or column, use LOOKUP, one of the lookup and reference functions. Consider the following scenario: you know the component number for a car part but not the price.

Aggregation refers to the process of summarising tabular data in Google Sheets. In Google Sheets, you may aggregate/summarize tabular data by computing the sum, average, maximum, minimum, median, and so on for all the values in a field.
