Got a .parquet file and nothing to open it with? You don't need to install Python, pandas, or any desktop software. The online Parquet viewer opens and reads Parquet files right in your browser — drag one in and you're looking at the data in seconds. Nothing is uploaded.
Open a Parquet file in your browser
The viewer runs a full data engine right inside the page, so it reads real Parquet files locally on your device — no server round-trip. Open a file from your computer, or paste a link to one hosted on the web, S3, or Hugging Face.
Once it's open you can scroll the rows, see the column types, sort and filter, search, run SQL queries, and export to CSV, JSON, or Parquet — all without the data ever leaving your device.
Why open Parquet online?
- No install. Nothing to download or set up — it works in any modern browser.
- No code. You don't need pandas or a notebook just to look at a file.
- Private. Your file is read locally; its contents are never sent anywhere.
- Handles remote files. Open a Parquet file by URL or from S3 without downloading the whole thing — it reads only the bytes it needs.
Big files and the desktop app
The web viewer is perfect for opening and exploring files quickly. For very large files or unlimited exports, the macOS app does the same work natively on your machine. New to the format? Start with what is a Parquet file.
