Hi, I’m using Power Automate Desktop and facing an issue with input/output variables.
When I use an input variable, it is always interpreted as [object Object] instead of a string,
which makes it hard to handle the value directly as text.

Example:
var val = ${MyInputVariable}
→ Output: [object Object]

But if I hardcode it:
var val = "MyInputVariable"
→ Output: "MyInputVariable"

What I need is to treat the input variable as a simple string value (e.g., "Sentence").
How can I properly convert or handle input/output variables in Power Automate Desktop so that they are recognized as strings instead of objects?

Thanks in advance!

Hi,

In power automate desktop the issue of [object Object] occurs because PAD variables can have different types such as Text, Number, List, Dictionary or Object. When we pass an object type variable into a script, JavaScript tries to convert it to a string, which results in [object Object]. This does not happen for the hardcoded string.

To resolve this issue, the variable must first be ensured as a Text type in PAD. We can do this using Convert variable action or by explicitly extracting the text property from an object.

For example, if your variable is a dictionary or JSON object, you can access the property you need like ${MyInputVariable["PropertyName"]}. If it’s a list or array, you can get a specific item using an index, e.g., ${MyInputVariable[0]}.

If we want entire object as a string, we can convert using JSON.stringify(${MyInputVariable}) in JavaScript action.
Following this approach ensures that your input/output variables are recognized as strings and can be used directly in scripts or text actions without showing [object Object].

Thanks!
