Importance of filtering and sorting in different activities

 What is the importance of sorting and filtering?

Essentially, sorting and filtering are tools that let you organize your data. When you sort data, you are putting it in order. Filtering data lets you hide unimportant data and focus only on the data you're interested in.

Sorting and filtering offer two different ways to customize the view of data in your sheet. You can't do both at the same time so it's best to determine in advance which option will help more.
Sorting lets you organize all or part of your data in ascending or descending order. Note that you cannot undo a sort after it has been saved so you'll want to make sure that all of your rows in your sheet, including parent rows in a hierarchy, are ordered the way you want before saving.

Filters allow you to show or hide information on your sheet based on selected criteria. They're useful because they don't change the overall layout of your sheet. You can also save filters and share them with anyone who is shared to the sheet. You can even set default filters on your sheet so that when shared users open that sheet, they see the same view.
