Microsoft Power Automate to "Empty" an AudioFile field

Time to execute: approx. 10 min.

Microsoft Power Automate became the successor of Anywhere365 Timer Jobs. Microsoft Power Automate is capable to do the exact same thing, plus many more things from which you can benefit to deliver the best possible experience to your customers.


Sometimes it may be necessary to clear a populated field in one of your SharePoint lists. For example an AudioFile selected in one of your IVR Interactive Voice Response, or IVR, is a telephone application to take orders via telephone keypad or voice through a computer. By choosing menu options the caller receives information, without the intervention of a human operator, or will be forwarded to the appropriate Agent. Questions needs to be cleared to have a silent anouncement or revert back to the Text-To-Speech mechanism.

In Power Automate replacing a file in a field with "nothing" takes a special approach. Using the custom value "-1" as your AudioQuestionId (and a change on the List settings containing your audio file), will make sure the field will be cleared when being processed by Power Automate.

Getting started
