Iterating over Excel files and add rows from CDS

Hi Power Automate Community!

 

I'm in the middle of building a Flow and seems to have found a blocked path.

 

I have a OneDrive for Business folder with multiple only headers Excel files (expenses_{employeeName}.xlsx). I need this flow to be able to iterate over those files and add rows from CDS. The problem is I can't find a way to dynamically set the Excel file location in the Add rows connector.

 

Is there a workaround for this?

Hi @PowerAppsDaniel 

 

Sorry for the bad news but I don't think you're able to define it. The connector will always add data to the end of the table :(.

 

Sorry for the bad news.

Re: Iterating over Excel files and add rows from CDS

Hi @manuelstgomes,

 

Thank you for your answer but that isn't an issue in this case. I want to add rows to the end of the tables. The problem is I want to loop through the different Excel files and add rows to those in each iteration. In the loop, I want to be able to dynamically set the Excel file so that each iteration refers to a different Excel file (1 iteration = 1 employee = 1 Excel file).

Hi @PowerAppsDaniel 

 

OH!! Now it makes sense :).

 

To cycle through the files you can use the following strategy:

 

 

The issue comes when you're trying to use the Excel action. When you define it with dynamic values, the columns won't be fetched, since Power Automation doesn't know the file until it's running so it cannot fetch the columns. You'll get something like this:

So you can't add directly the value.

The only solution to this is to map directly by name all excel files and, since Power Automation can see the structure, then you have fields to insert data. I know this sucks but it's the only way that I see that you can insert data.

 

Hope this helps you.

Hi @manuelstgomes,

 

What do you mean by "map directly by name all excel files and, since Power Automation can see the structure, then you have fields to insert data", could you elaborate a bit more on this idea?

 

Thanks.

Hey @PowerAppsDaniel 

 

Sure. Here's what you get when you can define the full path and the table of the Excel:

The issue with dynamically fetching Excel files is that you can't pre-define the tables and the structure so you can't add to the fields.

 

Does it make sense?
