How to Analyze a Chat Export: Stats and Clean Text (Free)

By ZeroFee Tools · October 4, 2026 · 6 min read

Your chat exports hold more than messages: they hold patterns. Who talks the most in the group chat? How many photos were shared last year? When did the conversation actually start? The free chat export cleaner answers all of that. Upload your WhatsApp .txt export and it strips encryption notices and system messages, then shows total message counts, a per-sender breakdown with each person's share of the conversation, the media count, and the date range from the first to the last message, plus a cleaned transcript you can copy or download.

It is built for the jobs where pasting is awkward. Very long exports that would be painful to copy, quick texting analysis for fun (who really dominates the group chat), summarizing activity before archiving a conversation, or preparing a clean record for documentation. For quick paste-based cleaning without stats, the WhatsApp chat cleaner takes pasted text directly. After cleaning, a word counter pass tells you the transcript's length.

Which chat exports does this tool support?

Any plain-text chat export where each message starts with a timestamp, such as the WhatsApp .txt export from iPhone and Android. Upload the .txt file with the button, or paste its contents if you prefer. Files are read locally in your browser and never sent to a server.

The core format is simple: plain text where each message begins with a timestamp, which is exactly what WhatsApp produces on both iPhone and Android when you export a chat. Exports made with media attached work as well, but the attached photos are not in the file anyway, so choosing the without-media export gives you the smallest file with identical text. If your export comes from a messenger app with a similar timestamped layout, it will likely parse too, since the detection is pattern-based rather than brand-specific.

Upload works through a file button, and pasting remains available as a fallback for quick jobs. There is deliberately no server upload: your browser reads the file locally with JavaScript. That design choice has two benefits. First, privacy: your private chats never travel over a network. Second, size: even very large exports process fine because nothing is uploaded or downloaded during analysis. You can even disconnect from the internet after the page loads and the tool keeps working.

What statistics does the chat analyzer show?

Total message count, a per-sender table with message counts and each person's share of the conversation, the number of media placeholders, and the date range from the first to the last message. Stats are computed from cleaned messages, so system lines never inflate the numbers.

The headline numbers are straightforward: total messages in the export, a per-sender table showing each person's message count and their percentage share of the conversation, the number of media placeholders (photos, videos and voice notes shared), and the date range from the first message to the last. Together they sketch the shape of a relationship or a group: who initiates, who reacts, how active the chat was and when it went quiet.

Crucially, the stats are computed from the cleaned messages, so encryption notices and system lines never inflate the numbers. A group chat where an admin added twenty members will not credit those system lines to anyone. Fun uses include settling the "who texts more" debate with actual data, summarizing a community group's year, or checking activity before you archive an old conversation. Practical uses include documenting customer chat volumes or preparing a tidy record for legal and HR files, where a clean transcript plus a date range is exactly what is asked for.

Is uploading a chat file to the tool private?

Yes. Your file is read by JavaScript in your browser tab and never sent anywhere: there is no upload, no account and no server copy. You can even disconnect from the internet after the page loads and the tool keeps working, which proves nothing leaves your device.

Completely local. When you pick the file, JavaScript in your browser tab reads it and does the parsing on your device. There is no upload step, no account, no server copy and nothing retained after you leave. The "upload" wording on the button just means "read this file"; the bytes never leave your machine. That is why the tool asks for a file instead of a paste box in the first place: browsers can read large exports directly, and your private chats never travel over a network.

If you want to be thorough, clear the file after you finish to wipe it from the page, and download the cleaned .txt for your own records. The privacy model also means there is no history or dashboard to manage. Each analysis is a fresh, self-contained session, which is exactly what you want when the content is personal. For everyday paste jobs where stats do not matter, the WhatsApp chat cleaner offers the same cleaning through a paste box.

This local-only design is also why the tool can offer a file button at all: there is no server to maintain and no storage to pay for, so the feature stays free and unlimited. Your workflow is simply export, upload, review, download, and optionally clear the file when you are done.

How to analyze a chat export in 5 steps

1. Export the chat. In WhatsApp, export the conversation without media to get a small .txt file.
2. Upload the file. Click the upload button on the tool page and select your exported .txt.
3. Click Analyze chat. The tool strips system messages and encryption notices, then computes the statistics.
4. Review the stats. Check total messages, the per-sender breakdown, media count and date range.
5. Download the cleaned text. Save the cleaned transcript as a .txt file for your records.

6 practical tips for chat export analysis

• Export without media for the smallest file. The text is identical, and the file stays light and fast to analyze.
• Use it for group chat debates. Per-sender stats settle "who texts the most" with real numbers.
• Check the date range before archiving. It tells you exactly what period the export covers.
• Remember stats exclude system lines. Member additions and encryption notices never inflate anyone's count.
• Clear the file when done. One click wipes the export from the page for extra peace of mind.
• Pick paste mode for tiny jobs. For a handful of messages, the WhatsApp chat cleaner is faster than exporting a file.
