Is my WhatsApp chat uploaded to a server?

No. All parsing and analysis run entirely in your browser. Your chat file is never sent to ToolAdda or any third party.

What file format does WhatsApp export?

WhatsApp exports a plain-text .txt file (often named _chat.txt) when you choose Export chat → Without media. Each line contains a timestamp, sender name, and message.

Does this work with iOS and Android exports?

Yes. The parser supports both iOS bracket format [DD/MM/YYYY, HH:MM:SS] and Android dash format DD/MM/YYYY, HH:MM - Sender: message, plus common locale variations.

What statistics can I see?

Message count per person, share percentage, words and characters, busiest hour and day, weekday activity, top emojis, word cloud, average and median response times, media/link counts, conversation initiators, and active-day streaks.

Can I analyze group chats?

Yes. Group chats work the same way — every participant appears as a separate sender in the statistics.

Why are some messages missing?

Very old exports or unusual locale formats may parse differently. Try switching the date locale setting (DD/MM vs MM/DD) or ensure you exported Without media as a .txt file.

Analyze WhatsApp Chats Privately

WhatsApp's built-in export gives you a plain-text log of every message. ToolAdda's Chat Analyzer turns that file into rich statistics — who talks the most, when you're both active, favourite emojis, common words, and how fast each person replies — without uploading anything to the cloud.

How to export from WhatsApp

Open the chat → tap ⋮ (Android) or chat name (iOS)
Choose Export chat → Without media
Save or share the _chat.txt file
Upload it here and click Analyze Chat

Is my chat uploaded to a server?

No. Parsing and all analytics run 100% in your browser using JavaScript. Your messages never leave your device.

iOS vs Android export format?

iOS uses brackets: [DD/MM/YYYY, HH:MM:SS] Name: message. Android uses dashes: DD/MM/YYYY, HH:MM - Name: message. Both are supported automatically.

Group chat support?

Yes. Every participant appears as a separate sender with their own message count, words, emojis, and response times.

What is response time?

When person B sends a message after person A, the time gap is counted as B's response time (within the selected window, default 24 hours). Averages and medians are shown per person and per pair.

Can I export the report?

Yes. Download a JSON summary with sender stats, top words, emojis, and activity data for your records.

Why zero messages detected?

Ensure you exported Without media as .txt. Try changing the date format setting if your device uses US MM/DD/YYYY dates.
