Your complete
NX walkthrough.

1. Install, connect and scan

1. Install NX from the download section. The Store listing is awaiting approval; the preview ZIP uses manual installation.
2. Pin NX in Chrome and click its icon. It opens or reuses WhatsApp Web.
3. If WhatsApp shows a QR code, link your own account from WhatsApp on your phone. Never share the QR code or a sign-in code.
4. Wait for WhatsApp to finish loading. NX scans automatically and shows Connected to WhatsApp.
5. Use Sync contacts on Overview whenever you need a fresh scan. Auto scan checks periodically while the panel is open.

NX needs desktop Chrome 142 or newer. It can only read information available in the connected session; it cannot reveal hidden phone numbers.

2. Reconnect or switch WhatsApp accounts

If you see WhatsApp disconnected, click Reconnect WhatsApp near the top of NX. It opens or reuses a WhatsApp tab and scans again. You do not need to reinstall the extension.

1. Open the account icon → Connection if you have several WhatsApp tabs.
2. Refresh the tab list and choose the intended tab.
3. Wait for the new scan before editing contacts or starting a workflow.

When the selected tab disappears, NX clears the old contact view. Scanning can reconnect to an available WhatsApp tab. Notes and custom fields are separated by WhatsApp account, so switching accounts does not copy one account's details into another. Group and bulk actions still require a fresh review for the current account.

3. Overview and quick filters

Conversations shows the available chat count; Address book shows contacts outside the chatlist. Saved, Unsaved, Groups, Business and Enterprise provide shortcuts into the relevant export selection. Country buttons narrow the list by estimated calling-code region.

1. Click a summary tile or country button to open the corresponding export view.
2. Check the source, filters and preview before exporting.
3. Use Reset filters under More options if the result looks too small.

Country is inferred from phone calling codes, not a person's current location. Unknown saved status is excluded from Unsaved. Contacts without a resolved phone can appear in totals but be excluded from a phone-only export.

4. Contact list and Profile

Contacts → Profile now includes Your contacts, a searchable list of contacts from the scan. This list is separate from your WhatsApp conversations.

1. Type part of a name or phone number into Find a contact. Use the arrows to move through pages of results.
2. Click the contact you want. NX opens its local profile below the list without changing your open WhatsApp chat.
3. Add Contact notes, Tags, Email Address or Timezone. For tags, separate entries with commas.
4. Click Save properties. Changes also save when you leave a field.
5. Select another contact and return to confirm the saved details.

For example, add the tag “Follow-up” and a note such as “Requested pricing on Friday.” These are your own local notes; NX does not send them to the contact.

Open chat profile switches back to following the conversation currently open in WhatsApp. Selecting a contact from the list pauses that automatic following, so a background chat change will not replace the profile you are editing. Open a group conversation in WhatsApp to edit its group profile.

If the list is empty, reconnect and sync first. A scan only includes contacts available to that session. Notes are stored in this Chrome profile; they are not an online contact backup and do not automatically move to a different computer.

5. Create and use custom fields

Profile stores a value for one contact. Fields defines the reusable labels you want to fill in. Creating a field does not automatically populate its value for every person.

1. Open Contacts → Fields.
2. Choose CONTACTS or GROUPS. Contact fields apply to individual profiles; group fields apply to an open group profile.
3. Enter a name such as Lead source, Customer ID or Event date, then click Add.
4. Return to Profile and select a contact, or use Open chat profile for an open group.
5. Find the new input, enter its value and click Save properties.

Example: create a CONTACTS field named Lead source. For one contact enter “Website”; for another enter “Event”. Each profile keeps its own value. Custom fields use text, so dates should be entered consistently if you plan to sort them later.

Remove hides a field from the form; existing stored values are retained. Adding the same field name again can reveal the earlier values. Custom properties are included as structured custom_data in applicable table exports; vCard carries its supported name, number, email and note fields.

6. Export from Chatlist, Groups or Labels

1. Open Exports and choose a source.
2. Chatlist: choose Chatlist contacts or All available contacts.
3. Groups: select one or more accessible groups. Members load when you start the group export, so the first preview can be empty.
4. Labels: select a WhatsApp Business label available to your account. If none are detected, confirm you are connected to the correct Business account.
5. Apply Unsaved Contacts Only, Unread Only, Country or Name Contains as needed. More options includes Phone Numbers Only and Reset filters.
6. Review Preview contacts. Select specific rows for a subset; without a row selection, all matching contacts are exported subject to plan limits.
7. Choose the file format beside the export button, then download.

Read the completion notice for the actual exported count. The Free plan allows up to 15 contacts per export or selected group. Pro removes NX export item caps; WhatsApp data availability and permissions still apply.

7. Choose the right file format

• Excel (.xlsx): review and organize a spreadsheet.
• CSV (.csv): import a flat table into a compatible tool; map its required columns and preserve telephone numbers as text.
• vCard (.vcf): import supported contact details into an address book. NX includes only valid international phone numbers.
• JSON (.json): process the exported fields in your own structured-data workflow.
• HTML (.html): open a searchable report locally in a browser.

Exports are generated in your browser. Uploading a downloaded file to another service or sending it to someone is a separate sharing action. For examples, read the format comparison and Excel guide.

8. Privacy mode: the eye icon

1. Click the eye icon at the top of NX.
2. Confirm that the icon is highlighted and the Privacy on banner appears.
3. NX blurs contact details in its panel and masks the WhatsApp chatlist and open conversation.
4. Click the eye again to restore the visible details.

The WhatsApp mask is tied to that tab and is reapplied after a reload while the browser session remains active. If WhatsApp is disconnected, NX still hides its own contact details and tells you that WhatsApp masking is unconfirmed. Reconnect to apply the pending setting.

Privacy mode is a visual screen-sharing aid, not encryption. It does not redact downloaded exports, prevent notifications outside the page, or hide information in other applications. Check your screen before sharing it.

9. Bulk Assign Labels

1. Open Tools → Bulk Assign Labels.
2. Choose a label available in the connected WhatsApp Business account.
3. Paste international phone numbers or import a CSV/text list. NX matches the numbers to available existing chats; it does not create conversations to unknown numbers.
4. Click Preview changes and review the matched recipients and label.
5. Click Confirm & run only when the review is correct. Watch the progress; use Stop to prevent later actions.

The Free plan permits up to five bulk items per run. A stop does not undo actions already completed. Correct an invalid or unmatched number before retrying; check the current state if an outcome is uncertain.

10. Archive, unarchive or delete chats

1. Open Tools → Bulk Archive / Delete Chats.
2. Choose Archive chats, Unarchive chats or Delete chats.
3. Select available chats, or paste/import numbers and click Select matching chats.
4. Choose the pause between actions, then Preview changes.
5. Review the list. Deletion additionally requires the displayed DELETE confirmation.
6. Click Confirm & run. Use Stop if you need to stop before the next action.

Archive and unarchive change the chat's archive state. Delete removes the selected local chat and is not an undoable archive operation. Preserve any information you need before confirming deletion. The Free bulk limit is five items per run.

11. Clone WhatsApp Group

1. Open Tools → Clone WhatsApp Group.
2. Select the source group and click Load group preview.
3. Review the proposed new group name and description; edit them if required.
4. With a verified Pro plan, click Confirm & create group.
5. Copy the returned invitation link and share it yourself with the intended people.

Clone creates a new group with the requested name and description. It does not copy message history or automatically enroll everyone from the original group. If group creation succeeds but a later step fails, inspect the result before retrying to avoid creating another group.

12. Bulk Remove Members

1. Open Tools → Bulk Remove Members and select a group you administer.
2. Click Load members. Search and select the intended members. Your own account and group admins are protected.
3. Choose a pause and click Preview changes.
4. Download roster backup and acknowledge that you saved it. A roster file is not a backup of messages or media.
5. Type the exact group name shown in the review.
6. With Pro active, click Confirm & run. Review the per-member results and download the result CSV.

This tool keeps the group and its invite link; it removes only the reviewed targets. Completed removals are not automatically reversible. NX rechecks membership and permissions, and stops when the action cannot be confirmed. Stop prevents later actions after the current request.

13. Add Members / Invite

1. Open Tools → Add Members / Invite, select the group and Load members.
2. Paste international numbers, one per line, or import a CSV/text file up to 2 MB with a phone/number column.
3. Click Preview changes. Review invalid entries, duplicates and people already in the group.
4. Confirm that the selected people agreed to join, and type the exact group name.
5. With Pro active and suitable group permissions, click Confirm & run.
6. Review each result. Some people may require an individual invitation because of their privacy settings. Copy and share that invitation yourself.

Get group invite link provides the group's invitation link when your account is allowed to retrieve it. NX does not send invitation messages. It does not bypass group capacity, member privacy settings or WhatsApp restrictions. Use Download result CSV to keep the added, invitation-required, skipped, failed or not-attempted results.

14. Destroy Group / Teardown

This is a destructive admin workflow for a group you intend to retire. Use Bulk Remove Members instead if you want to keep the group.

1. Open Tools → Destroy Group (Teardown), select the intended group and Load group preview.
2. Confirm the group name, membership and your admin status.
3. Download roster backup. Save any required messages or media separately.
4. Acknowledge the backup and type the exact group name.
5. With Pro active, choose Confirm & start teardown.
6. Monitor the sequence: revoke the invite, remove members, leave, then delete your local group chat. Use Stop to halt later steps.

Completed steps cannot be automatically undone. NX does not erase copies of conversations held by other people. If membership, permission or account changes, load a fresh preview instead of resuming an outdated review.

15. Sign in, subscribe and manage billing

1. Open the account icon. Enter your email and click Email a sign-in code.
2. Enter the six-digit code from your inbox and click Verify & sign in.
3. Choose Monthly, Annual or Lifetime if you want Pro. Review the final price and terms in Stripe Checkout.
4. After confirmed payment, return to NX. Your plan refreshes automatically; Refresh subscription requests another check if needed.
5. Use Open Billing Manager to view invoices, update payment details, change available recurring plans or cancel a recurring subscription.

Current prices are USD 7.99/month, USD 59/year and USD 79 once for Lifetime, excluding applicable taxes. Monthly/Annual support two linked WhatsApp numbers and Lifetime supports three. Link this WhatsApp number activates the current number; Deactivate this WhatsApp number releases that activation. Free supports one number.

Pending or failed payments do not unlock Pro. Cancellation stops future renewal; access follows the confirmed billing status. The seven-day refund policy covers eligible first purchases. Sign out of NX account signs out of NX billing, not WhatsApp.

16. Language, diagnostics and support

Account → Language includes English, Auto (Browser), Bahasa Melayu, Español, Português, Deutsch and Français. The setting updates supported navigation and account labels; some workflow text remains English. Your choice is saved in this Chrome profile.

Under Diagnostics & local data, enable diagnostic logging when troubleshooting, reproduce the issue, then Download diagnostics. The file records supported event categories and the extension version; it is not a contact backup. Review any file before sending it to support.

Use the question-mark icon for Help & support, or the Tutorial button to return here. Contact hi@nxtractor.com with the NX version, your sign-in email if relevant, and a description of what happened. Hide private contacts in screenshots. Never send passwords, login codes, card numbers or WhatsApp QR codes.

17. Common problems and fixes

No contacts in Profile

Reconnect and sync. Clear the contact search. Choose a row from Your contacts, or open a conversation and use Open chat profile.

Fields looks empty

Create a field first, then return to Profile to enter a value. CONTACTS and GROUPS have separate field definitions.

Privacy seems unchanged

Look for the highlighted eye and Privacy on banner. If NX says WhatsApp masking is unconfirmed, reconnect the correct tab and try again.

A group preview has no contacts

For Exports → Groups, members load when you start the export. Group tools have their own Load group preview or Load members button.

An exported phone number is missing

Check Phone Numbers Only and other filters. NX cannot reconstruct numbers that WhatsApp does not expose. vCard additionally requires a valid international phone.

Payment succeeded but the plan still says Free

Use the same NX email used for checkout, return to the extension and Refresh subscription. If unresolved, contact support with the receipt reference; do not pay again just to troubleshoot.

18. Updates and keeping local data

Once the Chrome Web Store listing is approved, Store-installed copies receive Chrome-managed updates. Chrome controls their delivery timing. A manually installed preview does not receive Store updates.

1. For a preview update, keep the same extension folder and installation identity.
2. Replace the folder contents with the current preview package, then use Reload in chrome://extensions.
3. Reopen NX and reconnect WhatsApp.

Export any details you need before removing an extension, clearing browser storage or switching profiles. Installing the Store edition separately does not transfer the preview's local contact notes automatically. Sign in with your existing NX email to restore the billing plan associated with that account.
