WhatsApp Contacts Extractor Extension

The WhatsApp Number Extractor Extension is a browser extension designed to help you organize and manage phone numbers from your WhatsApp chats. Unlike some other tools, this extension works entirely on your local machine and does not scrape data directly from WhatsApp Web. Instead, it processes a text file that you manually export from a chat or group.

Here is a breakdown of how the extension functions:

1. Input: The extension’s primary function is to read a .txt file that you provide. It looks for sequences of characters that resemble phone numbers.
2. Normalization: Once potential numbers are found, the extension cleans them by removing spaces, dashes, and parentheses to create a standardized E.164 format (e.g., +256770123456). It also attempts to identify and validate numbers based on a predefined list of country codes.
3. Output: The extracted numbers are categorized into “Valid” (clean, formatted numbers) and “Need Review” (numbers that couldn’t be fully formatted). You can then download these lists as separate CSV files for use in other applications.

How to Use the Extension

Using the WhatsApp Number Extractor is a straightforward, two-step process:

1. Export Your Chat: Go to the group or chat you wish to extract numbers from on WhatsApp Web. Click the three dots at the top right, select “More,” and then choose “Export chat” and “Without media”. This will save a text file to your computer.
2. Process the File: Open the extension’s popup in your browser. Click the “Select exported .txt” button and choose the file you just saved. The extension will automatically process the numbers and display a summary of its findings. You can then download the extracted numbers in CSV format.
