17 October - Spreadsheet Day
Spreadsheet Day has been celebrated since 2010. This is the date when the first VisiCalc spreadsheet program for personal computers was released - October 17, 1979.
A spreadsheet is a computer program that can capture, display and manipulate data arranged in rows and columns. Spreadsheets are one of the most popular tools available with personal computers. A spreadsheet is generally designed to hold numerical data and short text strings.
A spreadsheet is an easy way to store all different kinds of data. Excel was the first application to use a toolbar. The maximum length of an Excel formula is 8,192 characters. Any cell can contain only up to 32,767 characters. Up to 4,000,000,000 (yes, billion) formulas can depend on a single cell.
The UNIQUE function is a quick way to remove duplicate lines from a table of data in a spreadsheet. It returns the unique rows in the provided source range while discarding duplicates. The rows are returned in the order in which they first appear in the source range.
