# Import Google Analytics 4 data into Mammoth

> Connect Mammoth to Google Analytics 4 with a Google sign-in, pick a GA4 property, import report tables, and keep late corrections with Replace all data.

The Google Analytics 4 (GA4) connector imports reporting data from a GA4 property into Mammoth as a dataset. You sign in with Google and pick the property to read. Open it from **Data Library** > **New dataset** > **Connectors** and search for **Google Analytics 4**. Project Admins create the connection; Project Editors can start datasets from a connection the project already has. Which connectors you can add depends on your plan.

## What you can bring in from GA4

- Report tables for the property you pick. Each is a fixed set of dimension and metric columns read from GA4.
- Account tables, such as accounts and properties.
- Only the columns you tick.

The dataset can refresh daily or only when you ask.

## Before you connect Google Analytics 4

You need a Google account with access to the GA4 property you want to report on.

## Connect Google Analytics 4 to Mammoth

1. Go to the **Data Library**, click **New dataset**, and choose **Connectors**.
2. Search for **Google Analytics 4** and click its tile. The connector workspace opens with the **Chat** showing. See [Connect a database or app](https://mammoth.io/docs/learn/get-data-in/connect-a-source/) for the shared steps.
3. In the chat, click the button to sign in with Google and allow Mammoth access.
4. Pick the GA4 property (profile) to read.



## Pick GA4 tables and columns

1. In **Tables**, open a table and tick the columns you want. They gather in **Your table**.
2. Click **Preview 100 rows** to check the data.

## Save GA4 data as a dataset

1. Click **Save as dataset**.
2. Enter a **Dataset name** and pick the folder under **Save in**.
3. Under **Keep it up to date**, choose **Daily** or **Manual**.
4. Click **Save**.

## Choose a GA4 update method that keeps corrections

Choosing **Daily** creates a [Dataset Refresh](https://mammoth.io/docs/learn/automate/refresh-a-dataset/) automation that you can reschedule later.

After you save, the dataset's **Update method** offers these options:

| Update method | What it does |
| --- | --- |
| **Replace all data** | Rebuilds the dataset from the source on every refresh |
| **Add new rows only** | Keeps your rows and adds rows above the last value of a **Key column** |
| **Keep only the newest rows** | Empties the dataset, then brings in rows since the last refresh (needs a **Key column**) |

GA4 keeps correcting the numbers of recent days after it first reports them. If you pick a date as the **Key column**, each day is imported only once, so those corrections never arrive, and Mammoth warns you about this. Choose **Replace all data** to always have the corrected numbers.

## Troubleshoot GA4 connections

| Symptom | Likely cause | Fix |
| --- | --- | --- |
| A property isn't listed | Your Google account can't see it | Check the account you signed in with has access to the property in Google Analytics |
| Recent days don't match GA4 | A date key column skips late corrections | Switch the **Update method** to **Replace all data** |
