This is actually a pretty common ask here. However it can differ from person to person but here is what you want to use.
NOTE: If you say something doesn't work its good to explain what doesn't work and errors etc. Also, the pictures aren't coming through, not your fault its an issue in the platform, but when you paste them in, if you can't see them neither can we, so you may need to paste (delete) paste again lol until it shows :-).
Ok pseudo steps
1. Trigger (when an email arrives shared mailbox)
2. Apply to each to go through Attachments
3. Inside use a Condition to check if the current Attachment (in the loop) ends in PDF
In the yes side
--Use the Predict Action selecting your model and passing in your PDF content from the Attachment
--You get back all the data you have setup. I don't know what it is but id's, numbers, names etc in a structured way that you can then use in Excel
----NOTE: Make sure your Excel sheet has a Table around the Data you want so that you can statically link your incoming data to it, that or you need to use Create Table and then Dynamically bind to it with the item property and a JSON that describes your row
--Use Add a row to a table Action.
------Based on the NOTE I have, in your design if your excel has the Table, then bind all the dynamic properties from the Predict action to your Excel Columns, that or in your item property build a json of all the properties (columns) and values from the Predict
And done, its honestly that simple
If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.
Thank you!
