When Zach is inputting numerical data into an electronic worksheet, he is creating a spreadsheet. A spreadsheet is a digital tool used to organize, manipulate, and analyze numerical data through a grid of rows and columns. This format allows for various calculations, data management, and even the creation of formulas to automate tasks.

Spreadsheets are commonly used in business for budgeting, financial analysis, and project management, making them essential for data handling in many fields. The ability to easily update and reorganize data is a key feature of spreadsheets that distinguishes them from databases, charts, and presentations. Each of those alternatives serves a different purpose: databases are structured collections of data, charts visually represent data, and presentations compile information in a slideshow format for sharing or reporting.
