+### Configure JSON deserialization options
+
+Previously, when opening a workbook JSON object into the Spreadsheet using the `openFromJson` method, the entire workbook, including all features specified in the JSON object, was processed and loaded into the Spreadsheet. 
+
+Now, you have the option to selectively ignore some features during the opening of the JSON object by configuring deserialization options and passing them as arguments to the `openFromJson` method. This argument is optional, and if not configured, the entire workbook JSON object will be loaded without ignoring any features.
+
+```ts
+spreadsheet.openFromJson({ file: file }, { ignoreStyle: true });
+```
+
+| Options | Description |
+| ----- | ----- |
+| onlyValues |  If **true**, only the cell values will be loaded. |
+| ignoreStyle | If **true**, styles will be excluded when loading the JSON data. |
+| ignoreFormula | If **true**, formulas will be excluded when loading the JSON data. |
+| ignoreFormat | If **true**, number formats will be excluded when loading the JSON data. |
+| ignoreConditionalFormat | If **true**, conditional formatting will be excluded when loading the JSON data. |
+| ignoreValidation | If **true**, data validation rules will be excluded when loading the JSON data. |
+| ignoreFreezePane | If **true**, freeze panes will be excluded when loading the JSON data. |
+| ignoreWrap | If **true**, text wrapping settings will be excluded when loading the JSON data. |
+| ignoreChart | If **true**, charts will be excluded when loading the JSON data. |
+| ignoreImage | If **true**, images will be excluded when loading the JSON data. |
+| ignoreNote | If **true**, notes will be excluded when loading the JSON data. |

 ### External workbook confirmation dialog
 
 When you open an excel file that contains external workbook references, you will see a confirmation dialog. This dialog allows you to either continue with the file opening or cancel the operation. This confirmation dialog will appear only if you set the `AllowExternalWorkbook` property value to **false** during the open request, as shown below. This prevents the spreadsheet from displaying inconsistent data.
