Noob trying to rename PDFs based on contents in the PDF

Hi. I've been beating my head against the screen, trying to figure this out. I've even used ChatGPT Hazel helper to try and accomplish it. Specifically, I want Hazel to:

Extract the Merchant, Date, and Amount from the text inside the PDF.
Rename the files using this pattern: [Merchant] - [Date] - [Amount].pdf.
Here’s what I’ve done so far.

The PDFs are from my Chase bank. They all have a line for Merchant, Date, Amount.

I jsut can't figure out how to do the custom tokens. I'm sorry if this has been answered elsewhere (I'm sure it has). I've looked at other questions / use cases and frankly, I just don't understand it enough. I'm hoping if I can do it here with this specific case, I'll be able to figure it out.

This is what the ChatGPT Hazel Helper suggested I do:

Set Up Rules:
In the conditions, I’m using Contents contain match with the following regular expressions:
For Merchant: Merchant (?P<Merchant>.+)
For Date: Date (?P<Date>\w+ \d{1,2}, \d{4})
For Amount: Amount \$(\d{1,3}(?:,\d{3})*(?:\.\d{2})?).

The tokens (blue bubbles) are not being created, even though I’ve typed the regex patterns in the "Contents contain match" field.
Without these tokens, I can’t use them in the rename action, and my files end up named literally as [Merchant] - [Date] - [Amount].pdf.

I know it shouldn't this hard, I just don't know how to do it. lol. thx in advance.

This is what I get from PDF when I copy and paste it from the PDF.

ChatGPT is wrong here. You do not type in regexes. You need to drag/click on the tokens to add them. Please read the manual on match patterns, and not rely on things like ChatGPT.

Thanks Mr. Noodle. I tried reading the forums and the FAQ before I went to our digital overlords. I couldn't quite get it frankly.

Would you mind telling me or demonstrating (for the thousandth time I'm sure) what I would do to capture everything after a word like, Amount, please? I know that I want to turn that into a token, but I have a brain lock I guess where I can't quite picket up from the literature.

Thx again and apologies for my ignorance.

Let's say, for merchant, it's the word "merchant:" followed by some text then the end of the line. You can use a pattern like:

Code: Select all: Merchant: (• merchant)

(• merchant) is a custom text attribute. It's pattern would be "anything" if you want to match any text (up to the end of the line). You can use more specific patterns as needed.
