What is is null in Google Sheets?

Is Null is part of the SQL-like QUERY function language in Google Sheets. QUERY reads a range with SELECT, WHERE, GROUP BY, ORDER BY, and LABEL clauses instead of nested spreadsheet functions.

When to use it

Use QUERY clauses when you want SQL-style filtering, grouping, or labels on a table in one formula.

When to skip it

Skip QUERY when FILTER, SORT, and UNIQUE already express the logic with less string syntax to maintain.
