title: How to insert an empty string into a field in a flow action in Microsoft Power Automate
body: <p>How do you insert an empty string into a field in a flow action in Microsoft Power Automate? Google results I've found say to use a 'null' expression and it should empty the field. However, it didn't work when I was using the Excel (Business) connector for an 'update a row' action. The field retained its original value instead of being empty.</p>
