Convert SharePoint List Attachments to PDF

[Supertension]

Hi, I'm completely new to Power Automate and don't really know where to start.

I have a SharePoint list and each item will have one jpeg file attached to it.  I'm trying to create a flow so that every time a new list item is created, the jpeg attachment is converted to a pdf file and the pdf file is added to the list item as a second attachment.

I have signed up for Adobe PDF Services but after hours of trying different things I'm getting nowhere.

Can anyone point me to any example flows so that I can learn?

Thanks you.

Hi,

Your flow would be configured like this.

1) Sharepoint's "When item is created" trigger

2) SharePoint's "Get Attachments": Note this will simply return a list of attachments for the created item, not the actual attachment content.

3) SharePoint's "Get Attachment content": This will return the actual picture attachment. The previous step will return an array of attachments (even if you only have 1 attachment because it doesn't know how many there will be). Therefore this action will be created within an apply to each unless you use a first() expression to avoid this (only do this if you are sure there is only one attachment).

4) Convert the image to content to PDF. Encodian's Convert to PDF action will handle image file types or use a service you already have.

5) SharePoint "Add Attachment" action: add the PDF output from Encodian or other connector to the list item as an attachment

Hi Alex,

Thank you so much.  I managed to get everything to work first time using Encodian's convert to PDF.

You said I could use a first() expression.  Could you please so me how to do this?  I have a attached a copy of my flow so you can see what it look like just now but I's like to simplify it to just deal with one attachement per list item if possible.

Thank you again.

Hi David, apologies I dont see messages unless i am tagged in them.

This is about data structure. The Get attachments action can return multiple attachments. In order for that to work, it has to return an array of attachments....because it is designed that way, it returns an array even if you have only a single attachment (like you suggested in your case).

Since you are then passing the array to the next action, Power Automate will automatically put a for each loop around it i.e. it will loop through the array even if the array has only a single item in it.

To avoid this, you can use the first() function which returns the first item in the array. In your get attachment content action, instead of inserting the dynamic data straight from get attachments, insert an expression. The expression would be first() and within the brackets you insert the dynamic value of the previous action.
