Find Links in Modern Page

Summary

Script will take a csv file that contains url to SharePoint sites and analyse the site pages to see if any of the pages have hyperlinks. For every hyperlink in a page this gets output to a row in a csv that is delimited by a pipe

The script reads a list of SharePoint sites from a CSV file, connects to each site and extracts all pages within the specified lists. For every page content that contains an anchor tag, it captures both 'Title' field value (from Page metadata) along with any href tags present in its body text using regex matching, then writes these details into a new CSV file named after today’s date.

Note: Above last paragraph of description uses AI to describe the script.
