Introduction
Row and column grouping helps you organize your spreadsheet by hiding and showing groups of rows or columns. This makes large sheets easier to read and work with by collapsing sections you don't need to see all the time.
When you have monthly sales data for a whole year and want to collapse each quarter to focus on one at a time.
When you track project tasks and want to hide completed tasks to focus on pending ones.
When you create a budget sheet and want to group expense categories to see summaries easily.
When you have a large table and want to hide detailed rows or columns temporarily for presentations.
When you want to organize data by departments and collapse each department's data for clarity.
