# Download datasets as CSV or Excel from the Data Library

> Download one Mammoth dataset, several ticked datasets or a whole folder as CSV or an Excel workbook, stack same-column datasets into one file, with limits.
>
> Applies to: Where: Data › dataset panel › Download

**Download** saves a dataset's rows as a CSV file or an Excel workbook. Find it in the dataset panel's icon strip, a row's **⋯** menu, or the selection bar when you tick several datasets under **Data** in the left sidebar. A folder's **Download folder** gets every dataset inside it.

## Download one or several datasets

1. Click **Download** in the dataset panel, or tick several datasets and click **Download** in the selection bar.
2. Choose a format:

   | Option | One dataset | Several datasets |
   | --- | --- | --- |
   | **CSV file** / **CSV files (.zip)** | One .csv file | A .zip file with one .csv file per dataset |
   | **Excel workbook** | One sheet | One file with one sheet per dataset |
   | **Stack the ones with the same columns into one file** | | Datasets with identical columns are stacked into a single file. Appears when some have the same columns, and says how many files you get. |

3. Confirm. While the file is prepared, the dialog shows, for example, "3 of 5 ready. The file saves on its own when it's done." If you leave the page, a notification brings you the file when it's ready.

- On a dataset with several Views, the dialog says which View it downloads: the one you were last in.
- Raw files that have not become datasets are left out ("Raw files have no rows to download yet").

For other ways to get data out, see [Download data](https://mammoth.io/docs/learn/share-and-export/download/).

## Limits

| Limit | Value |
| --- | --- |
| Datasets in one download | 200 ("One download holds at most 200 datasets. This one has 240.") |
| Size of one download | 1 GB ("This download is over 1 GB. Pick fewer datasets.") |
