Comply data into an excel file using Google search (IS2024)

I need help in collecting emails of participants in an academic conference, using open online sources. Using the name and research affiliation of the researchers available in the conference program, I need you to compile an Excel file the following info: name, affiliation, email, conference session name. Again, of these bits of information, only email address is currently missing, which you would be asked to locate using Mr. Google. This is a time-critical project, I would need this file within a week since the start of the project. The approximate number of emails to collect is about 500-700.
