Spreadsheet revisionBy Charlotte Neal

Spreadsheeto A 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.

o Most people use spreadsheets for

calculations. However, you can also make diagrams

based on the data.

o The most popular spreadsheet software is

Microsoft Excel, but there is also Apple Numbers, as

well as many more.

Worksheet

o A worksheet is a page of a spreadsheet.

o In Excel, you have a workbook – one document – with one or more worksheets in.

Cells, Rows and Columns

o A cell is a single box in the spreadsheet.

o A row is a horizontal line of cells.

o A column is a vertical line of cells.

Functiono Functions 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

o Formulas are equations the spreadsheet calculates. They always begin with equals signs.• + is for adding• - is for subtracting• * is for

multiplication• / is for division

o You can use numbers or cells as values.

Macroso A macro is a series of

commands and functions that are recorded on Excel, and can be run whenever you need.

o You 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 formattingo With conditional

formatting, you can set cells so features such as colours and fonts change when certain things are, or are not entered.

o For example, you can use a spreadsheet as a quiz – green for the correct answer and red for wrong.

o You 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 cellso You 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.

o This is useful for if you’re doing a document that you don’t want to be edited.

o If you’re making a quiz, you could lock all cells except the answers.

o You can also set a password so that only people who know it can only unlock the worksheet.
