Compile 3,000 Company Contacts

I have to pull together a clean, reliable contact list for every company currently listed on the IDX (www.idx.co.id), Bursa Malaysia (www.bursamalaysia.com), and SET Thailand (www.set.or.th). There are roughly 1,000 companies on each exchange—about 3,000 in total—so accuracy and a consistent structure are critical.

The spreadsheet must contain three core columns in this exact order:
1. Company Name
2. Website
3. Email(s)

Because some firms publish more than one email address, place each email in its own cell to the right of the first one, rather than grouping them with commas. The final file has to be delivered as a single Excel (.xlsx) workbook so I can filter and run quick look-ups.

Feel free to use web-scraping, manual research, or a hybrid approach—whatever will give me a complete, deduplicated dataset with live, working URLs and valid email addresses (no generic “noreply@” or obvious bounces).
