This document discusses how to limit the data shown on a Microsoft Excel worksheet using filters and advanced filters. It explains that filters allow you to select rows to display based on rules, and that advanced filters allow finding unique values within a data set. Key steps include clicking the filter arrow in the column header, which displays filtering options and unique values. Options include sorting, clearing filters, and filtering by color or date. Advanced filters copy filtered data to a new location based on criteria in a separate range table. The overall goal is to summarize and analyze data by only viewing relevant rows.
