Spreadsheet revision By Charlotte Neal

Spreadsheet oA Spreadsheet is a computer program that works like a paper worksheet. You can put words and numbers into the cells, to store information and make calculations. oMost people use spreadsheets for calculations. However, you can also make diagrams based on the data. oThe most popular spreadsheet software is Microsoft Excel, but there is also Apple Numbers, as well as many more.

Worksheet oA worksheet is a page of a spreadsheet. oIn Excel, you have a workbook – one document – with one or more worksheets in.

Cells, Rows and Columns oA cell is a single box in the spreadsheet. oA row is a horizontal line of cells. oA column is a vertical line of cells.

Function oFunctions are something the user tells the spreadsheet to do to the data. SUM adds selected data. MIN finds the smallest in all the data. MAX finds the largest in all the data. AVERAGE finds a mean average of all the data. IF you set a condition, and two responses, as to whether the data in the condition was correct or not.

Formula oFormulas are equations the spreadsheet calculates. They always begin with equals signs. + is for adding - is for subtracting * is for multiplication / is for division oYou can use numbers or cells as values.

Macros oA macro is a series of commands and functions that are recorded on Excel, and can be run whenever you need. oYou select Record New Macro and a dialog box comes up. You select the name, shortcut key and description of the macro, then press OK. You perform the task you want it to do, then stop recording. Now when you select this macro, it will perform this task!

Conditional formatting oWith conditional formatting, you can set cells so features such as colours and fonts change when certain things are, or are not entered. oFor example, you can use a spreadsheet as a quiz – green for the correct answer and red for wrong. oYou could also use it so if a cell value is less than a certain amount, it turns red – this is good for working out expenditure.

Locking cells oYou can lock a whole worksheet, or just certain cells on a worksheet. This means that these cells cannot be edited. You can also set it so that they also cannot be selected. oThis is useful for if you’re doing a document that you don’t want to be edited. oIf you’re making a quiz, you could lock all cells except the answers. oYou can also set a password so that only people who know it can only unlock the worksheet.
