The Excel AutoComplete feature allows you to automate entering the same text into multiple cells. With AutoComplete, you enter the first few letters of a text entry into a cell, and Excel automatically completes the entry based on other entries that have already been in the current column:
Excel has a useful Data Validation feature to display messages and prevent incorrect cell entry. This feature works fine with manual data typing. However, validation messages will not be displayed if invalid data is entered into a cell by copying or filling; a formula in a cell evaluates to an invalid result; a macro enters invalid data into a cell; etc.
Usually, the data in Excel spreadsheets is presented in lists of rows, and each row represents a data record. Excel offers an easy way to work with this data type through a data entry form that Excel can automatically generate. This form of data works with a normal data range or a table.
When working with data in Excel spreadsheets, it is sometimes necessary to split text lines into columns. Excel offers many different functions for working with text strings, but you don't have to use formulas for this task:
You can greatly reduce data-entry problems in your workbooks by making Excel check entries before entering them in specific cells. To do so, you need to define restrictions and data-validation rules for those cells.
Named ranges (also known as defined ranges) are a powerful feature in Excel that allows you to assign a symbolic name to a cell, range of cells, or formula. These defined names are a convenient replacement for the address of a cell, data range, or formula in other formulas, charts, diagrams, shapes, etc.
When you paste or import data into the Excel spreadsheet, you might notice unusual symbols like a diamond with a question mark. The replacement character � (often a black diamond with a white question mark or an empty square box) represents an unknown, unrecognized, or unrepresentable character:
Dynamic, dependable, conditional, or calculated drop-down list in Excel implies that the contents of the drop-down list for the current cell should depend on values in the other cell and change dynamically when the value of the controlling cell changes.
Manual data entry into spreadsheets and especially entering data into text cells
leads to many errors. Excel data validation tools allow you to reduce the inaccuracy
of Excel data entry by restricting the set of possible values to a pre-defined list.
Users can select the item from a drop-down list with few choices instead of typing
text into the data entry form template.
