How to Analyze a Telegram Chat Export Privately: JSON, HTML, and a Wrapped-Style Recap

Telegram groups can run for years. That is great for inside jokes, trip planning, gaming squads, volunteer teams, and friend groups—but not so great when you want to answer a simple question like: when did this chat become most active?

A Telegram chat export analyzer helps turn a long message history into an understandable summary: message volume, participant activity, time-of-day patterns, and a Wrapped-style recap that gives the group something to talk about. The hard part is not finding stats. It is doing it without casually exposing everyone’s messages.

GroupGlow is designed for that boundary. Your Telegram export is analyzed in the browser. Raw chat text is not persisted to GroupGlow. If you later decide to share a report, the public link contains only the rendered aggregate snapshot you explicitly share—not a copy of the raw export or a transcript.

Start with the right kind of Telegram export

Telegram Desktop can export chat history in more than one format. For GroupGlow, use either:

• One JSON export for a structured, machine-readable chat history, or
• Telegram HTML export pages when your export is split into files such as messages.html, messages2.html, and so on.

If you have the option, JSON is usually the cleanest choice for a single structured export. HTML pages can also work when that is the export you already have, but keep all pages from the same chat together and do not mix them with a JSON file in one import.

GroupGlow is independent and is not affiliated with Telegram.

How to export a Telegram group chat from Telegram Desktop

The exact labels can change as Telegram Desktop evolves, but the general workflow is:

1. Open Telegram Desktop and navigate to the group chat you want to analyze.
2. Open the chat’s menu and choose the option to export chat history.
3. Select a format: JSON for one structured file, or HTML if you prefer the page-based export.
4. Choose the date range and content options appropriate for your group.
5. Finish the export and keep the resulting JSON file or the related HTML message pages together.

Export only a conversation you are allowed to use. A group export represents other participants, so it is worth telling the group what kind of recap you plan to make before you share it.

Make a Telegram Wrapped-style recap in GroupGlow

After exporting:

1. Visit GroupGlow for the product and privacy overview.
2. Open the GroupGlow app and choose Telegram.
3. Add one Telegram JSON export or select the matching Telegram HTML message pages. Do not mix JSON and HTML in the same import.
4. Check the import summary and confirm that you have permission to use the chat.
5. Generate the recap.

The result turns communication patterns into visual cards. It is meant to be a digestible group moment, not a searchable archive of what everyone said.

Privacy: summary first, transcript never

It is easy to confuse a “shareable recap” with a publicly hosted conversation. They are not the same thing.

GroupGlow calculates the report in the browser. Raw chat text stays browser-local and is not persisted to GroupGlow. You can download the resulting recap for your own use. If you explicitly create a public Wrapped link, it contains a rendered aggregate snapshot—such as cards, counts, activity patterns, and archetypes—not the Telegram JSON file and not a raw message transcript.

That separation is useful for a group that wants to laugh about its 1 a.m. message streak while keeping the actual late-night conversation in the group where it belongs.

Choose a recap that respects the group

Use aggregate insights to start a conversation, rather than treating analytics as a ranking of people. A few good ways to share:

• Post the busiest-hour card and ask whether the group should be trusted with decisions after midnight.
• Share a year-end recap alongside a reunion, graduation, or season wrap-up.
• Compare broad chat rhythms from different squads only if everyone involved is comfortable with it.
• Keep screenshots inside the relevant group instead of posting them publicly by default.

The point is not to expose who said what. It is to give the people who made the chat a compact way to remember it.

Troubleshooting your Telegram import

I have many HTML files. Which ones should I select?

Select the message pages from the same Telegram export, such as messages.html, messages2.html, and subsequent pages. Do not add unrelated HTML files from another chat.

I exported JSON and HTML. Should I upload both?

No. Choose one format for the import: one JSON export or the set of matching HTML pages. Mixing formats can duplicate or confuse the conversation history.

Does the public recap include my result.json file?

No. A public Wrapped link is optional and contains only the rendered aggregate snapshot that you explicitly share. It does not include the raw export or a chat transcript.

Is GroupGlow an official Telegram tool?

No. GroupGlow is independent and is not affiliated with Telegram.
