Access file contents via a url in a list

I have a SharePoint List (List A) and one of the 'columns' contains a link (url) to a document in another list (List B).
I'm trying to construct a flow that does the following. The Flow is triggered when a value in List A is modified (e.g. a status is set to true). I'd like to access the contents of the file in List B, convert it to PDF and save the new file in List B.

There doesn't seem to be an obvious way to do a "Get" to obtain the ID of the file in List B (via it's url) from List A.
I've tried 'Get Attachment Contents' and the flow ran ok, but the output was blank, because (I presume) the Action wasn’t able to get a handle for the source file in List B.
Any ideas?

Re: Access file contents via a url in a list

Hi @Anonymous @

The Url of the document contain the name of the file.

First, we can get the name from the Url in List A, then using the ‘condition’ to get the document from List B.

 I have made a test on my side, please take a try with the following workaround:

The Url which I created in List A is like this: file:///C:/Users/zhongys/Desktop/Daily words.docx

The compose action is to get the Name of the document.

The expression is : last(split(triggerBody()?['Url'],'/'))

Re: Access file contents via a url in a list

hI v-zhos-msft ,

Thanks for your reply, it is very much apprecaited. I spent some time experimenting with the teqnique you set out in your response but with no success. Unfortunately the url in the column in List A looks something like this...


I'm therefor not able to split off the file name and then compare it to each item in the list to find the item in List B.

What confuses me is that the url is a unique 'path' to the file so why can't that be used to get the contents of the file?

Re: Access file contents via a url in a list

spent a bit more time on this... If I hard code the ID of the document the flow works perfectly. So, the missing bit is how to derive the ID of the document from the url
