concat integer and '.pdf' for condition

Hi All,

I'm trying to set up a 'rename flow' for pdfs dropped into a folder in Sharepoint.

Any given pdf in question will always contain the string '1.pdf' to '72.pdf' in their file name, and I want the flow to detect when the file is dropped in a folder, get the file, and create a new file (with the original files content) in an 'Output' folder with the name 'Page1.pdf' to 'Page72.pdf'.

I'd rather not have to create an 'if' condition for 72 different scenarios, so I've instead got an:

'Initialize variable' action, named 'PageNumber' with an integer starting at 0,
a 'do until' action set to '72'
An increment variable action
Then a condition set to 'File Name' contains expression:

concat(variables('PageNumber'),'.pdf')

To test the flow, I'm dropping in a file named 'OM302120-001.pdf'.

The resulting file should be named 'Page1.pdf'

However, my condition is always returning false, and as such, no file is created.

Here is the full flow:

Part 1 Part 1 Part 2 Part 2

Any ideas where I'm going wrong?

Cheers in advance!

Chris

Hi
Does the 'File name' output -the one you are currently evaluating- contain the extension?
Hope this helps

@efialttes Hi efialttes, I believe so.

Here is a snippet of the output I'm getting for the "When a file is created or modified" trigger.
I've even tried not using the extension though, and just typing '001' into the contains 'field' (Not even using the 'PageNumber' variable. Still not working. I have a suspicion the flow is bugged and I'm trying to recreate it from scratch right now.

Cheers!

I've recreated your flow, the only difference I think is the fact I am using a different expression on my condition:

string(variables('PageNumber'))

The file I tested it with has number 1, so I would expect one only execution of the Do Until. The flow is working fine for me. See Flow execution...

...and Flow details:

If you manage to get the flow working once you rebuild it from scratch, please be aware of Do Unitl default limits, click on "Change Limits" if you need to change them

Hope this helps

@efialttes Hi efialttes, thanks for your help.

I actually ended up using the 'When a file is created or modified (properties only)' trigger, and used the 'Name' column in the document library, rather than the 'File Name' variable from my previous configuration, and this worked a treat.

But I can see your configuration would work as well, and I think I might end up doing it this way.

Thanks again for your help.

@v-alzhan-msft Thanks Alice, @efialttes's solution does indeed solve the issue, and I also came up with an alternate solution using the 'When a file is created or modified (properties only' trigger.

Cheers,
