await Excel.run(async (context) => {
const bindings = context.workbook.bindings;
bindings.load('items');
await context.sync();
for (let i = 0; i < bindings.items.length; i++) {
console.log(bindings.items[i].id);

Returns
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.BindingCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.BindingCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
toJSON(): Excel.Interfaces.BindingCollectionData;Returns
