The Scroll chart shows data for a long period in small scrollable time chunks. It makes easier to analyze data over a sufficiently long period in Microsoft Excel, Word or PowerPoint.
The Scroll chart displays some contiguous range of data from a large dataset. Using the provided Control tools, it is possible to add a scroll bar to the chart area and view the desired data range:

If you often need to adjust your data ranges so that your charts plot an updated data range, you may be interested in a trick that forces Excel to update the chart's data range whenever you add new data to your spreadsheet.

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:

The drop-down list is a handy feature provided by Excel data validation tools. Drop-down menus limit the possible choices and help to avoid mistakes. However, not so many Excel users know the Source field of the Data Validation dialog is a formula field. Formulas in the Source field should return the list of the values, but they are not necessarily a range or a list of options.
