Google Sheets filters are useful for focusing on specific data within a spreadsheet, making it easier to scan and make sense of information. To create a filter in Google Sheets, add column headers to the first row of your spreadsheet, click any cell or highlight the columns you want to filter, and then select "Create a filter" from the right-click menu or toolbar. A filter icon will appear next to every column heading that has been filtered, allowing you to easily view only specific rows of data based on cell values within a given column. Filters can be applied by condition, using options such as Text is exactly, Date is after, and Greater than, or by values in the column. You can also create a filter view in Google Sheets, which allows you to apply filters to only your view of a shared spreadsheet, making it easier to share data with others. Additionally, Google Sheets integrates with Zapier's automation tools, allowing users to automate workflows and keep their data up to date across apps.
