Hi All,

I have a use case where in i would want to check dynamically in a document library if a column exists in that particular library and if not create that particular column.

is that possible through power automate?

Any help would be appreciated.

Hi @Jayant_2203,


Yes, that would be possible. You could retrieve the existing columns via an Send an HTTP action and the Fields method in the REST API and use a filter array to check if your custom column already exists.


Below is an example of that approach.


1. Send an HTTP request uses this URI. In this example I am using a string variable ListName which is storing the name of the list.



2. Filter Array uses the results collection of the output body.



In the where I am comparing the InternalName of the field to the name of our custom field. In my example that name is stored in a string variable called FieldName.





When the output of the Filter Array is empty you could create the new column.
