Manipulate Data (Spreadsheets)
Muhtasari
A spreadsheet often holds far more data than you need to look at all at once. Manipulating data means rearranging and trimming it so the answer to a question jumps out: sorting a class list into mark order, or pulling out only the customers in one city. The data itself does not change; you simply change which rows you see and the order they appear in.
In this lesson you will learn to sort data into ascending or descending order on one column or several, and to search and filter so that only the rows matching your criteria remain. You will use the logical operators AND, OR and NOT, the comparison operators such as greater than and not equal to, and wildcards for matching partial text. These are the everyday tools that turn a wall of numbers into a clear report.
