Extract Chart Data to Excel

I need the numerical series displayed in a single interactive chart on a public webpage captured exactly as shown today and handed back to me in a clean Excel (.xlsx) file. This is a one-time job—no recurrent scraping or scheduling once the data is safely in the spreadsheet.

The chart is rendered dynamically via JavaScript, so you may have to rely on browser developer tools, Selenium, Python, or any solution you prefer to pull the values accurately. I will supply the URL as soon as we start. Every plotted number must be copied; missing or rounded figures are not acceptable.

Please structure the spreadsheet so each column represents a series (if more than one exists) and use intuitive headers that mirror any labels visible on the chart. When you finish, send me the Excel file and a brief note confirming the extraction method you used for reference.
