Can I export WhatsApp group contacts without saving them to my phone?

Yes. Mastros reads the member list WhatsApp Web shows you and writes it to a file; nothing is added to your phone's contacts.

Does the export include phone numbers of people who hid them?

No. WhatsApp decides what you can see. If a number is hidden from you in the group, it is hidden from Mastros too.

Is this an Excel file?

It is a CSV, which Excel and Google Sheets open directly with one column per field. JSON and JSONL are there if you need them for a script or a CRM import.

How many contacts can I export on the free plan?

The free plan covers 100 profiles and 100 messages a month. Paid plans with bigger limits are listed on the WhatsApp page.

Will the people in the group know?

No. Mastros sends nothing, reads nothing it is not shown, and does not join or leave anything on your behalf.

Export WhatsApp contacts to Excel or CSV with Mastros: open a group in WhatsApp Web, pick Group Members in the Mastros panel, press save, and the whole list is written to a CSV file you can open in Excel or Google Sheets. It includes members whose numbers are not saved in your phone, because WhatsApp Web shows them to you as a member of the group and Mastros only reads what is on your screen.

What you get

All members of any group or community you belong to, with the name WhatsApp displays, their role, and the phone number where WhatsApp shows it.
Your chat list, exported the same way with the Recent Contacts tool: names, last messages and numbers.
CSV, JSON or JSONL. CSV opens in Excel, Google Sheets, Numbers and every CRM import.
Hidden phone numbers stay hidden. If WhatsApp hides a number from you, Mastros cannot show it and does not try.
No WhatsApp Business API, no bot, no broadcast: Mastros never sends a message to anyone on the list.

It only reads. Mastros never sends messages, never follows, likes or replies, never asks for a password or an API key, and processes every row in your browser. Nothing you export is sent to Mastros.

How to export WhatsApp group contacts to Excel

01Add Mastros for WhatsApp from the Chrome Web Store.
02Open web.whatsapp.com and the group whose members you need.
03Open the Mastros panel, choose Group Members, and press save.
04Open the CSV in Excel or Google Sheets, one member per row.

Export unsaved WhatsApp contacts

Members you have never saved show in WhatsApp Web with their number and the name they set. Mastros exports them as they appear, so a group of 800 people becomes a sheet of 800 rows in one run, without adding anyone to your phone's address book.

WhatsApp Business

The same steps work in WhatsApp Web for a WhatsApp Business account. Mastros does not use the Business API and does not need one. To save the photos and videos a group shares as well, use the WhatsApp media downloader; to save a conversation, see export WhatsApp chat to Excel or CSV.
