Firestore Data Analyzer

Firebase doesn't show you your data.
This does — inside Chrome, in 2 minutes.

The Firebase console gives you a raw document browser. Firestore Data Analyzer gives you tables, aggregation, trend charts, and one-click export — in a Chrome side panel, connected directly to your own Firestore project.

Read the User Guide Privacy: local-only, no tracking

Works with every Firebase plan, including the free Spark plan. No server, no admin keys — your data never leaves your browser.

Everything the console is missing

Each feature is documented in the User Guide.

📂

Auto-discovered collections

Browse your Firestore data in the Firebase console and the extension quietly learns your collection names — pick them from a dropdown, no typing.

How it works →
📋

Fast, scrollable table view

Large collections stream in progressively — first rows appear in under a second, with a live "Loaded N / M" progress count and infinite scroll.

Table view →
🧮

Group & aggregate

Tick the fields you care about and get instant group-by counts with bar charts. Results recompute live as you change fields.

Aggregation →
📈

Trend charts

Date fields are auto-detected and charted — see records per day at a glance, switch chart types with one click, and focus with a Top N picker.

Analytics →
📤

Export to JSON, CSV, Excel

Download whole collections in the format your workflow needs — full-fidelity JSON, spreadsheet-ready CSV, or Excel.

Export →
🛡️

Security-rules helper

Hit "permission denied"? The extension generates a safe, read-only, UID-scoped rule for the exact collection you tried — copy, paste, retry.

Up and running in four steps

The full walkthrough lives in Getting Started.

  1. Install the extension

    Add Firestore Data Analyzer to Chrome from the Chrome Web Store.

  2. Connect your project

    Open your project in the Firebase console. A small banner guides you to your project's Settings page, where the extension picks up the connection details by itself — nothing to copy or paste.

  3. Open the side panel & sign in

    Click the toolbar icon or the floating Analyze handle, then sign in with an email/password account from your own project's Firebase Authentication.

  4. Load a collection

    Pick a collection from the dropdown and explore: table, aggregation, charts, export.

Private by architecture, not by promise

Data flows directly between your browser and your own Firebase project. The extension has no servers and no tracking — nothing you do in it is sent anywhere, and it talks to nothing except Firebase itself. Read the privacy policy.
