단순히 데이터를 긁어오는 것을 넘어서, 추출된 결과물을 나중에 다시 읽고 검색하기 편하게 텍스트를 깔끔하게 정돈해 주는 느낌입니다. 핸드폰 용량을 비우기 위해 오래된 왓츠앱 방을 정리할 때 특히 유용하며, 기록 보관용으로 이만한 툴이 없는 것 같습니다.

The export options make this extension stand out. Being able to save WhatsApp Web data as Excel, CSV, or JSON could be really useful when there’s a lot of information to organize. The bulk media download is another practical feature, especially for chats with lots of photos and documents. I also like that everything runs in the browser and doesn’t require API credentials. The fact that it only works with information already visible in WhatsApp Web makes its limits pretty clear, which is helpful when deciding what to export.

I like that the export options go beyond just saving chat text. Being able to package photos videos and documents into one ZIP with a CSV manifest makes archiving a conversation much easier. The fact that everything is processed in the browser is reassuring too. I also appreciate that it only works with data already visible in WhatsApp Web rather than trying to access hidden account information.

I needed to save a bunch of photos and documents from a WhatsApp group, and this made it way easier than downloading everything one by one. I also like that it puts everything into a ZIP with the files organized, instead of leaving my Downloads folder a mess. Super handy for backing up group media or exporting chat info when you need it.

I like having a simple way to save a whole chat’s media instead of opening every photo or video separately. The ZIP download is especially convenient since it keeps everything together and includes the details in a separate file. Exporting chat information to CSV or Excel is useful too when I need to sort through a lot of messa

This extension makes exporting WhatsApp Web data much easier. I like that it can organize information into Excel, CSV, JSON, or ZIP files instead of requiring manual copying. The interface is straightforward, and having different export modes for members, chats, contacts, and media makes it useful for different workflows.

honestly pulling phone numbers from client groups took me forever.this addon dumps visible contact details straight into clean excel sheets.i dont need to copy paste numbers by hand anymore.scrolling back to load older chats felt slightly clunky though...still it runs locally without leaking thier data to servers.this tool became a total lifesaver for my sales work!!

I needed to save a bunch of photos and files from a WhatsApp chat, and doing it one by one was such a pain. This extension made it much easier to grab everything together instead of spending forever clicking through each file. Pretty handy if you use WhatsApp for work and need to keep chat files organized.

I manage a few large WhatsApp groups, and manually saving contacts or downloading shared media used to be a total nightmare. This tool is a massive time-saver. I can easily scrape group member lists straight into an Excel file and bulk-download all the photos, videos, and documents into a single ZIP folder in just a few clicks. It works smoothly right in the browser and makes handling WhatsApp data completely painless.

This WhatsApp extension looks like an interesting tool for managing conversations and media more conveniently. Having features for downloading media and organizing chat information in one place could be useful for users who work with WhatsApp regularly. I appreciate the idea of bringing practical tools together to make everyday tasks easier and more efficient.

Pretty useful if you need to organize information from WhatsApp Web. I like that it can export group members, contacts, and chat messages without having to copy everything manually. The Excel and CSV options make it easy to keep the data organized, and having the extraction run directly in the browser is a nice touch.

I installed it to pull chat media as one ZIP instead of saving files one by one. Tried it, removed it, came back. The ZIP with CSV manifest is what I like most. Group member export works too. Reads only what WhatsApp Web has loaded. I'll keep it for archiving old chats.

This extension helps me extract WhatsApp data, whether from contacts or groups, and export it in formats like Excel, CSV, or JSON. It can also download media, documents, and other files from chats.I like that it works directly with WhatsApp Web and doesn't require external account connections. The fact that it operates client-side is also a nice privacy feature.And thanks to the developer of this extension.

Finding a browser utility for WhatsApp Web that doesn't send your sensitive contact list or message logs to an external server is rare. Mastros operates entirely on the client side inside your browser tab. It cleanly extracts loaded member lists and chat history directly to your device without requiring account access or API tokens.
