# View and manage dataset
You can view, review, edit, or delete your datasets once you have imported them. You can also start a new experiment using a dataset you have imported.
## View a dataset
To view an imported dataset:
1. On the H2O LLM Studio left-navigation pane, click **View datasets**.
2. You will see the datasets table with a list of all the datasets you have imported so far. Click the name of the dataset that you want to view.
:::info
For more information about the dataset details you see on the table above, see [dataset configurations](import-dataset.md#configure-a-dataset).
:::
## Dataset tabs
You will see the following tabs that provide details and different aspects of your dataset.
- **Sample train data** : This tab contains sample training data from the imported dataset.
- **Sample train visualization:** This tab visualizes a few sample training data from the imported dataset in a question-answer format; simulating the way the chatbot would answer questions based on the training data.
- **Train data statistics:** This tab contains metrics about the training data (e.g., unique values) from the imported dataset.
- **Summary:** This tab contains the following details about the dataset.
| Name | Description |
| ----------- | ------------------------------------ |
| **Name** | Name of the dataset. |
| **Problem type** | Problem type of the dataset. |
| **Train dataframe** | Name of the training dataframe in the imported dataset. An imported dataset can contain train, test, and validation dataframes. |
| **Train rows** | The number of rows the train dataframe contains. |
| **Validation dataframe** | Name of the validation dataframe in the imported dataset. An imported dataset can contain train, test, and validation dataframes. |
| **Validation rows** | The number of rows the validation dataframe contains. |
| **Labels** | The labels the imported dataset contains. |
## Edit a dataset
To edit an imported dataset,
1. On the H2O LLM Studio left-navigation pane, click **View datasets**. You will see the datasets table with a list of all the datasets you have imported so far.
2. Locate the row of the dataset you want to edit and click the <Icon>more_vert</Icon> Kebab menu.
3. Select **Edit dataset**.
4. Make the desired changes to the dataset configuration. You can also [merge the dataset with an existing dataset](merge-datasets) at this point.
5. Click **Continue** and review the dataset with your changes.

## Delete a dataset
When a dataset is no longer needed, you can delete it. Deleted datasets are permanently removed from the H2O LLM Studio instance.
:::caution
You can only delete datasets that are not linked to any experiments. If you wish to delete a dataset that is linked to an experiment, first [delete the experiment](../experiments/view-an-experiment#delete-an-experiment), and then delete the dataset.

1. On the H2O LLM Studio left-navigation pane, click **View datasets**.
2. Click **Delete datasets**.
3. Select the dataset(s) that you want to delete.
4. Click **Delete** to confirm deletion. |
