title: How to insert dropdown or checkbox in Excel using Javascript API?
body: <p>I'm following the doc (<a href="https://dev.office.com/reference/add-ins/excel/excel-add-ins-reference-overview" rel="nofollow noreferrer">https://dev.office.com/reference/add-ins/excel/excel-add-ins-reference-overview</a>) to build an Excel add-in. The add-in needs to populate an Excel table column with either dropdown or checkbox for the user to select actions to be done on the table row. I can't seem to find any API to insert dropdown/checkbox in Excel spreadsheet. Could someone advise how I could do that?  Thanks! </p>
