Extract data from Power Query

Hi, I've been fighting with powerquery (pq) bc I need to extract specific numbers from a pdf, it has hundreds of pages and the numbers are always at the same spot, but they're not spreadsheets, they're invoices.

I've tried pq but it makes nonsense sheets trying to convert the text to a normal sheet, but I can't find how to keep just the number I need and toss the rest of the info
