Parquet Viewer is a free, browser-based tool for inspecting Apache Parquet files locally without uploading them to a server. It takes .parquet files as input and displays their rows in a browsable table, supporting filtering and export. The tool runs entirely on the client side, ensuring data stays on the user's device.
