An exclamation mark. To refer to cell B56 on Sheet3 you would do this:
=Sheet3!B56
Sheet2!B2
The Name box.
An absolute reference. An absolute cell reference.
A 3d reference refers to a worksheet, a column and a row, to identify a particular cell in a workbook. The following is a simple example, where the worksheet name is in the reference and is followed by an exclamation mark before the cell address: =Sheet1!A3 * 10
If you have a value in cell A1 on Sheet1 and you want it to appear in Sheet 2, you use a formula. So in a cell on Sheet2 type: =Sheet1!A1 Sheet1 is the sheet name. The exclamation mark separates it from the cell reference. Now whatever is in the cell A1 on Sheet1 will appear in the cell with that formula.
color coding
An exclamation mark. If you are on Sheet1 and you are referencing the cell A3 on Sheet2 it would be done in the following way: =Sheet2!A3
Columns are referenced by letters and rows by numbers, so the answer is D3.
Cells are the fundamental element of a worksheet. All formulas are put into them. Most functions and formulas will reference cells on the worksheet. So cells are extremely important in Excel. Without them, you do not have a worksheet.
I am not sure what you are asking, since you link cells, and not tabs. But, if you want to know how to link to a cell on another worksheet, add the name of the worksheet with an apostrophe (!) before the cell name. If you want to reference cell B13 from Sheet1 on Sheet2, enter the following formula on Sheet2: =Sheet1!B13.
You use the name of the worksheet, followed by the exclamation mark, followed by the cell you want. So if you are on Sheet2 and want to reference the cell C20 on Sheet1 your reference would be: Sheet1!C20
The cell reference will be in the top left of the spreadsheet, showing what cell is the currently active cell. Also, the column heading and row heading are highlighted.
It is the reference to the cell formed where column B meets row 20.
