Aspone.cells set cell data format Setting Display Formats of Numbers and Dates

Setting Display Formats

Using Microsoft Excel:

1. Right-click on any desired cell and select Format Cells option.
   A dialog appears that allows your to set the display formats of any kind of value.

In the left side of the above figure, you can see that there is many categories of the values like general, number, Curre Ncy, Accounting, Date, time, Percentage etc. Aspose.cells supports all of these categories to set the display format of numbers or dates.

Aspose.cells provides a class,WorkbookThat's represents an Excel file.Workbook class contains A  Worksheetcollection  that allows to access all worksheet in the Excel File. A worksheet is represented by The  worksheet  class.   Worksheet  class Provides A  Cells   Collection. Each item in The  Cells  collection represents an object Of  Cell  class.

Aspose.cells provides the SetStyle method in the Cell class which is used to set the form Atting style of a cell. Also, style object of style class can used that further provides some useful prope Rties to configure font settings.

Using Built-in number Formats

Aspose.cells offers some built-in number formats to configure the display formats of the numbers and dates. These built-in number formats can be applied by using The  setnumber Span class= "Apple-converted-space" > method of The  Style Span class= "Apple-converted-space" > object. All built-in number formats is given unique numeric values. Developers can provide any desired numeric value to The  setnumber Span class= "Apple-converted-space" > method of  Style  object and hence the display format is applied. This approach was more faster. The built-in number formats supported by Aspose.cells is given below:

Value	Type	Format String
0	General	General
1	Decimal	0
2	Decimal	0.00
3	Decimal	#,# #0
4	Decimal	#,# #0.00
5	Currency	$#,# #0; $-#,# #0
6	Currency	$#,# #0; [red]$-#,# #0
7	Currency	$#,# #0.00;$-#,# #0.00
8	Currency	$#,# #0.00; [red]$-#,# #0. XX
9	Percentage	0%
10	Percentage	0%
11	Scientific	0.00E+00
12	Fraction	# ?/?
13	Fraction	# /
14	Date	M/d/yy
15	Date	D-mmm-yy
16	Date	D-mmm
17	Date	Mmm-yy
18	Time	h:mm am/pm
19	Time	H:mm:ss am/pm
20	Time	h:mm
21st	Time	H:mm:ss
22	Time	M/d/yy h:mm
37	Currency	#,# #0;-#,# #0

41	Accounting	_ * #,# #0_; _ * "_; _ @_
42	Accounting	_ $* #,# #0_; _ $* "_; _ @_
43	Accounting	_ * #,# #0.00_; _ * "?? _ ;_ @_
44	Accounting	_ $* #,# #0.00_; _ $* "?? _ ;_ @_
45	Time	Mm:ss
46	Time	H : Mm:ss
47	Time	mm:ss.0

The following output is the result of executing the code below.

Using Custom Number Formats

To define your own customized format string to set data display format, use the setcustom method of The Style object. This approach was not as much faster as the first approach discussed above but it was more flexible.

The following output is the result of executing the code below.
