How to Format Cells using GetStyle and SetStyle Methods
Apply different kinds of formatting styles on cells to set background or foreground colors, borders, fonts, horizontal and vertical alignments, indentation level, text direction, rotation angle and much more.
How to Use the GetStyle and SetStyle Methods
If developers need to apply different formatting styles to different cells then it’s better to get the Style of the cell using Cell.GetStyle method, specify the style attributes and then apply the formatting using Cell.SetStyle method. An example is given below to demonstrate this approach to apply various formatting on a cell.
How to Use Style Object to Format Different Cells

- Access the newly added Style object

- Assign the configured Style object to your desired cells
This approach can greatly improve the efficiency of your applications and save memory too.

- Start Index, the index of the character that the selection starts from.
- Number of Characters, the number of characters to select.
The Characters method returns an instance of the FontSetting class that allows developers to format the characters in the same way as they would a cell as shown below in the code example. In the output file, in the A1 cell, the word ‘Visit’ will be formatted with the default font but ‘Aspose!’ is bold and blue.
