load(options)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(options?: Excel.Interfaces.CustomXmlPartLoadOptions): Excel.CustomXmlPart;Parameters
Provides options for which properties of the object to load.
Returns
load(propertyNames)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames?: string | string[]): Excel.CustomXmlPart;Parameters
- propertyNames
-
string | string[]
A comma-delimited string or an array of strings that specify the properties to load.
Returns
load(propertyNamesAndPaths)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths?: {
select?: string;
expand?: string;
}): Excel.CustomXmlPart;Parameters
- propertyNamesAndPaths
-
{ select?: string; expand?: string; }
propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.
Returns
setXml(xml)
Sets the custom XML part's full XML content.
setXml(xml: string): void;Parameters
- xml
-
string
XML content for the part.

const customXmlPart = context.workbook.customXmlParts.getItem(xmlPartIDSetting.value);
// The setXml method does a whole-for-whole replacement
// of the entire XML.
customXmlPart.setXml("<Reviewers xmlns='http://schemas.contoso.com/review/1.0'><Reviewer>John</Reviewer><Reviewer>Hitomi</Reviewer></Reviewers>");

await context.sync();
const readableXml = addLineBreaksToXML(xmlBlob.value);
$("#display-xml").text(readableXml);
await context.sync();
}
});
toJSON()
Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.CustomXmlPart object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.CustomXmlPartData) that contains shallow copies of any loaded child properties from the original object.
toJSON(): Excel.Interfaces.CustomXmlPartData;Returns
