# List custom data

> Every CSV or JSON dataset uploaded to your account.

The **Manage Custom Data** slide-over lists every dataset you've uploaded — its name, row count, column count, file size, and upload date. Open it from the **Manage** button next to the **Dataset** label in the **Data Query** widget's **Custom Data** source.

## What's on a row

| Field        | Description                                       |
| ------------ | ------------------------------------------------- |
| `name`       | The label you gave the dataset when you saved it. |
| `columns`    | The columns parsed from the file header.          |
| `row_count`  | Number of data rows.                              |
| `file_size`  | Size of the uploaded file.                        |
| `file_name`  | The original file name, if one was provided.      |
| `created_at` | When the dataset was first saved.                 |
| `updated_at` | When the dataset was last changed.                |

## Quick actions

From the **Manage Custom Data** slide-over you can:

* **Edit** — change the data or rename the dataset. See [Update custom data](/custom-data/update).
* **Duplicate** — copy the dataset under a new name. See [Duplicate custom data](/custom-data/duplicate).
* **Delete** — remove the dataset. See [Delete custom data](/custom-data/delete).

## API

`GET /v1/custom-data` returns a lightweight list of your datasets, newest first. The list response omits `raw_data` because it can be large — fetch a single dataset with `GET /v1/custom-data/{id}` to include `raw_data`.
