Cardume: Contacts Exporter for WhatsApp Web – Excel & CSV

Export loaded WhatsApp Web contacts to CSV (opens in Excel), locally. Not affiliated with WhatsApp or Meta.

Open a group's participant list, click Cardume, review the list and save. That's it. 📊 Group members, a client's contact card, a supplier list… no more copying names and numbers one by one. ✍️❌ And the best part: everything happens on your device. Your contacts are never uploaded. 🔒 💪 Main features: 👉 Read only what you open ✔️ Group participants: export the people in a group's participant list ✔️ Contact info: export the name and number from an open contact card ✔️ Only the open panel is read. No messages, no chats, no background scanning 👉 Review before you save ✔️ Preview: see the names and numbers before anything is saved ✔️ Duplicates removed automatically, so each contact appears only once ✔️ Clear the preview whenever you want. It's gone as soon as you close the popup 👉 A spreadsheet that just works ✔️ CSV with Name and Phone columns, ready for Excel, Google Sheets, Numbers or your CRM ✔️ Phone numbers keep their format and leading "+" (no turning into 5.5E+12) 📞 ✔️ Protection against spreadsheet formula injection, built in ✔️ You choose where the file is saved on your computer 💾 ✋ Cardume only reads contacts that WhatsApp Web has already loaded on your screen. It never reveals hidden numbers, and you are responsible for having permission to use the contacts you export. 🎁 Free vs. Pro 🆓 Free ✔️ Read and preview as much as you like. It never uses your quota ✔️ CSV export ✔️ 3 exports every 24 hours ✔️ Up to 15 contacts per file ⭐ Pro: one-time purchase, no subscription ✔️ Every loaded contact in one file ✔️ No export quota ✔️ TXT export (phone + name, one per line) 💻 How to use: 🔸 Click "Add to Chrome" and pin Cardume to your toolbar 🔸 Open web.whatsapp.com and open a group's participant list or a contact's info 🔸 Click the Cardume icon, pick the panel and tap "Read loaded contacts" 🔸 Review the preview, choose where to save, and open the file in your spreadsheet 🚀 ❓ FAQ: 📌 Are my contacts uploaded anywhere? - No. Contacts are read and turned into a file right in your browser. They stay in the popup's memory until you clear or close it, and the saved file stays on your computer. 📌 Then why does the extension go online at all? - Only for the Pro account: sign-in with an e-mail code, checkout and the license check. Your contacts are never part of these requests. 📌 Does it read my messages? - No. Cardume only reads the names and numbers shown in the panel you opened. Messages and chats are never touched. 📌 Why are some numbers blank? - WhatsApp Web only shows the numbers it has loaded. If a number isn't displayed, Cardume leaves it blank instead of guessing. Long lists may also load partially, so scroll through them first. 📌 Why is there an apostrophe before the numbers? - It keeps your spreadsheet from turning phone numbers into math or formulas. Some importers show it; most hide it. 📌 Is it free? - Free with limits: 3 CSV exports every 24 hours, with up to 15 contacts each. For every contact, TXT and no quota, get Pro once and keep it. 📌 Is there a limit? - Up to 10,000 contacts and 4 MB per file. The preview shows the first 50. 📌 Is this an official WhatsApp tool? - No. Cardume works with WhatsApp Web but is not affiliated with, endorsed by or sponsored by WhatsApp or Meta. 🔐 Permissions, in plain words: 🔸 activeTab + scripting: read the open WhatsApp Web panel, only when you click "Read loaded contacts" 🔸 downloads: save the file you export 🔸 storage: remember your settings and the free export count 📪 Questions or ideas?
