## FormatCondition class

Represents conditional formatting condition.

```javascript
class FormatCondition;
```


### Example
```javascript
const { Workbook, CellArea, FormatConditionType, OperatorType, Color, SaveFormat } = AsposeCells;

//Instantiating a Workbook object
var workbook = new Workbook();
var sheet = workbook.worksheets.get(0);

//Adds an empty conditional formatting
var index = sheet.conditionalFormattings.add();
var fcs = sheet.conditionalFormattings.get(index);

//Sets the conditional format range.
var ca = new CellArea();
ca.startRow = 0;
ca.endRow = 0;
ca.startColumn = 0;
ca.endColumn = 0;
fcs.addArea(ca);

ca = new CellArea();
ca.startRow = 1;
ca.endRow = 1;
ca.startColumn = 1;
ca.endColumn = 1;
fcs.addArea(ca);

//Adds condition.
var conditionIndex = fcs.addCondition(FormatConditionType.CellValue, OperatorType.Between, "=A2", "100");
//Adds condition.
var conditionIndex2 = fcs.addCondition(FormatConditionType.CellValue, OperatorType.Between, "50", "100");

//Sets the background color.
var fc = fcs.get(conditionIndex);
fc.style.backgroundColor = Color.Red;

//Saving the Excel file
var uint8Array = workbook.save(SaveFormat.Xlsx);
