# Import files from Dropbox into Mammoth

> Connect Mammoth to Dropbox with a Dropbox sign-in, open a CSV, Excel, JSON or XML file as a dataset, and collect new Dropbox files on a schedule.

The Dropbox connector opens a file from your Dropbox account and saves it in Mammoth as a dataset. You sign in to Dropbox, so there are no API keys or credentials to manage. Open it from **Data Library** > **New dataset** > **Connectors** and search for **Dropbox**. 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 Dropbox

Files of these types: `.txt`, `.csv`, `.tsv`, `.psv`, `.xls`, `.xlsx`, `.xlsm`, `.xml`, `.json`, `.jsonl`, `.ndjson`, `.zip`, `.bz2`, `.gz`, `.tar`, `.7z`.

A spreadsheet file opens to its tabs.

## Before you connect Dropbox

You need a Dropbox account with the files or folders you want to import.

## Connect Dropbox to Mammoth

1. Go to the **Data Library**, click **New dataset**, and choose **Connectors**.
2. Search for **Dropbox** and click its tile. The connector workspace opens with the **Chat** connecting Dropbox.
3. Dropbox needs you to pick folders, which the chat can't do, so the chat's card hands you off. Click **Set up in the Data Hub**.
4. Sign in to Dropbox and click **Allow**. You're returned to Mammoth.
5. Under **Select Dropbox Files & Folders**, choose the ones Mammoth may read and click **Connect**. A folder includes everything inside it.
6. The connection is now ready to use in the chat.

If you already have a Dropbox connection, pick it under **Your connections** in the launcher instead. See [Connect a database or app](https://mammoth.io/docs/learn/get-data-in/connect-a-source/) for the shared steps.

## Open a Dropbox file and pick columns

1. In the left panel, browse your Dropbox folders and click a file to open it. A spreadsheet opens to its tabs.
2. Tick the columns you want. They gather in **Your table**.
3. If a file can't open in the panel yet, ask the agent in the **Chat** to import it.



## Save a Dropbox file as a dataset

1. Click **Save as dataset**.
2. Enter a **Dataset name** and pick the folder under **Save in**.
3. Click **Save**.

A dataset from a Dropbox file is saved once. Mammoth shows **Saved once. Scheduled refresh for files is coming.** A [Dataset Refresh](https://mammoth.io/docs/learn/automate/refresh-a-dataset/) automation can't re-read Dropbox files.

## Bring in new Dropbox files on a schedule

To keep adding files as they land in a Dropbox folder, use two automations:

1. A **File Collection** automation collects new files from the Dropbox folder into Mammoth on a schedule. See [What you can automate](https://mammoth.io/docs/learn/automate/).
2. A [Data Consolidation](https://mammoth.io/docs/learn/automate/consolidate/) automation adds the collected files to your dataset.

## Troubleshoot Dropbox connections

| Symptom | Likely cause | Fix |
| --- | --- | --- |
| Sign-in doesn't complete | You denied access or closed the tab | Start the connection again; Mammoth returns you after you click **Allow** |
| "Session expired. Please reconnect Dropbox." | The Dropbox sign-in expired | Start a new connection |
| "No files found." | The selected items contain no supported file types | Select a different file or folder, and check the file types listed above |
