The dataset page includes a table with the contents of the dataset, arranged by pages of 100 rows. You can navigate between pages using the buttons at the bottom of the table.
To have a nice and working Dataset Viewer for your dataset, make sure your dataset is in a supported format and structure. There is also an option to configure your dataset using YAML.
For more information see our guide on How to configure the Dataset Viewer.
At the top of each column you can see histograms representing the distributions of numerical values and text lengths. For categorical data there is also the number of rows from each class.
If you click on a bar of a histogram from a numerical column, the dataset viewer will filter the data and show only the rows with values that fall in the selected range. Similarly, if you select one class from a categorical column, it will show only the rows from the selected category.
You can search for a word in the dataset by typing it in the search bar at the top of the table. The search is case-insensitive and will match any row containing the word. The text is searched in the columns of string
, even if the values are nested in a dictionary or a list.
You can share a specific row by clicking on it, and then copying the URL in the address bar of your browser. For example https://huggingface.co/datasets/glue/viewer/mrpc/test?row=241 will open the dataset viewer on the MRPC dataset, on the test split, and on the 241st row.
To power the dataset viewer, every dataset is auto-converted to the Parquet format. Click on “Auto-converted to Parquet” to access the Parquet files. Refer to the Datasets Server docs to learn how to query the dataset with libraries such as Polars, Pandas or DuckDB.
You can also access the list of Parquet files programmatically using the Hub API: https://huggingface.co/api/datasets/glue/parquet.
For datasets >5GB, we only auto-convert to Parquet the first ~5GB of the dataset. In this case, an informational message lets you know that the Viewer is partial. This should be a large enough sample to represent the full dataset accurately, let us know if you need a bigger sample.
For the biggest datasets, the page shows a preview of the first 100 rows instead of a full-featured viewer. This restriction only applies for datasets over 5GB that are not natively in Parquet format.
