## Epilogue The parquet conversion is done by the [dataset viewer](https://huggingface.co/docs/dataset-viewer), and the list of parquet files is published through its [API](https://huggingface.co/docs/datasets-server/parquet). Join the growing community on the [forum](https://discuss.huggingface.co/) or [Discord](https://discord.com/invite/JfAtkvEtRb) today, and give the [dataset viewer repository](https://huggingface.co/docs/datasets-server/index) a ⭐️ if you’re interested in the latest updates! ## FAQ

What is the dataset viewer API?

The dataset viewer API is a lightweight web API for visualizing and exploring all types of datasets - computer vision, speech, text, and tabular - stored on the Hugging Face Hub. As datasets increase in size and data type richness, the cost of preprocessing (storage and compute) these datasets can be challenging and time-consuming. To help users access these modern datasets, the dataset viewer runs a server behind the scenes to generate the API responses ahead of time and stores it in a database so they are instantly returned when you make a query through the API. Let the dataset viewer API take care of the heavy lifting so you can:
Get instantaneous responses to information, such as the dataset splits, column and data types, about a dataset through a simple REST API.
Download and preview the first 100 rows of any dataset.
Access the dataset as parquet files.
