I have two PDF documents related to the same claim. The first one, already processed by Hazel, contains the claim number. The second one, arriving later, has additional claim details. I'd like to automatically merge these two PDFs into a single file whenever the second document becomes available. I don't have experience with automation tools or coding.

Hazel App has already placed the claim number in the comments of the first PDF like this: "Claim Number: 01-23-862-5607-1"

Any assistance would be greatly appreciated!

Hazel does not have an action to combine two PDF documents. You will need to use a script, Shortcuts or Automator to handle that part. Where is the claim number stored in the two documents?

The current code I'm utilizing is this, but it doesn't seem to work:

Code: Select all

#!/bin/bash

# Directory where Hazel places the processed PDFs
hazel_output_dir="/Users/dj/Library/CloudStorage/Dropbox/documents/My Scans/Insurance/Ameritas"

# Directory where the second PDFs with additional details arrive
incoming_details_dir="/Users/dj/Library/CloudStorage/Dropbox/Mac (2)/Downloads"

# Directory to store the merged PDFs
merged_output_dir="/Users/dj/Library/CloudStorage/Dropbox/documents/My Scans/Insurance/Ameritas"

# Function to extract claim number from PDF file comments metadata.
extract_claim_number() {
    pdf_file="$1"
    claim_number=$(pdftk "$pdf_file" dump_data | grep "Claim Number:" | awk '{print $3}')
    echo "$claim_number"
}

# Main loop to monitor for new PDFs and merge
while true; do
    # Find all PDFs in the incoming details directory
    for details_pdf in "$incoming_details_dir"/*.pdf; do
        # Extract claim number from the details PDF (you might need to adjust this based on how the claim number is presented in the second PDF)
        details_claim_number=$(extract_claim_number "$details_pdf")

        # Find the corresponding PDF in Hazel output based on claim number
        for hazel_pdf in "$hazel_output_dir"/*.pdf; do
            hazel_claim_number=$(extract_claim_number "$hazel_pdf")

            if [ "$hazel_claim_number" == "$details_claim_number" ]; then
                # Merge the PDFs using GhostScript (install if needed: `brew install ghostscript`)
                gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile="$merged_output_dir/${hazel_claim_number}_merged.pdf" "$hazel_pdf" "$details_pdf"

                # We need to create code to delete the processed PDFs after combining them.
                # mv "$hazel_pdf" /path/to/archive
                # mv "$details_pdf" /path/to/archive

                echo "Merged claim: $hazel_claim_number"
            fi
        done
    done

    # Sleep for some time before checking again (adjust as needed)
    sleep 60
done

You can have Hazel do the claim number extraction and general matching but in the end, you will need a script to combine the PDFs. Note that you can only pass in attributes as arguments for Apple/JavaScript, though.

Did you not see the script I added.

Yes, and you are doing Hazel's work of look for new files. Not sure why you are using Hazel here since the script is doing all that work.
