arvutuslehed

Arvutuslehed, commonly known as spreadsheets, are computer applications designed for organizing, analyzing, and storing data in tabular form. They consist of rows and columns, forming a grid of cells. Each cell can contain text, numbers, or formulas. Formulas are special entries that perform calculations based on the values in other cells, allowing for dynamic data manipulation. This ability to automatically update calculations when data changes is a core feature of arvutuslehed.

The primary purpose of arvutuslehed is to facilitate numerical analysis and data management. Users can input data, apply various functions and formulas, and then present the results in a clear, organized manner. Common uses include budgeting, financial modeling, inventory tracking, statistical analysis, and project management. The visual representation of data in rows and columns makes it easy to identify trends, patterns, and outliers.

Modern arvutuslehed offer a wide range of features beyond basic calculations. These include data visualization tools like charts and graphs, sorting and filtering capabilities, conditional formatting to highlight specific data points, and the ability to import and export data from various file formats. Collaboration features also allow multiple users to work on the same arvutusleht simultaneously. Popular arvutuslehed applications include Microsoft Excel, Google Sheets, and LibreOffice Calc.
