Transform how you work with Apache Parquet files. One double-click replaces dozens of command lines. Now available on macOS, Windows & Linux.
Every data professional knows the struggle. You receive a Parquet file, and suddenly you're writing Python scripts just to peek inside.
Double-click a Parquet file and watch your OS shrug. No preview, no Quick Look, no native support whatsoever.
Fire up Jupyter, import pandas, write df.head()... just to see the first few rows. Every. Single. Time.
Minutes turn to hours when you're constantly context-switching between data exploration and actual analysis.
When basic queries require code, you miss opportunities. Quick questions remain unanswered.
I built this app because I was tired of the friction. Now, exploring Parquet files feels as natural as browsing photos.
Open Parquet files instantly — no scripts, no notebooks, no waiting. Your data is just a double-click away.
Write queries directly in the app. Filter, aggregate, and explore — all powered by DuckDB under the hood.
Get instant insights: min, max, null counts, unique values, and more. Right-click any column for detailed stats.
Your files stay on your device. No uploads, no tracking, no surprises — just private, local analysis.
I built Parquet Reader because I needed it myself. Every feature comes from real frustration with existing tools. If you work with Parquet files daily, this app will change your workflow.

As we celebrate 10 Jahre Virtuelle Eisenbahn, it's clear that this technology has made a significant impact on the German railroad system. Looking ahead, we can expect further innovations and applications of Virtuelle Eisenbahn, including: german railroads 10 jahre virtuelle eisenbahn better
The concept of Virtuelle Eisenbahn was first introduced in Germany around a decade ago, as part of a broader effort to modernize the country's railroad system. The goal was to create a digital platform that could simulate rail operations, predict potential disruptions, and optimize traffic flow. Over the years, the technology has evolved, and its applications have expanded to cover various aspects of rail operations. If you are arguing why this era or
That is the ironic question. Ask any Eisenbahner (railway worker). Many real train drivers say the simulator is harder . In real life, your senses help you. In the virtual world, you rely purely on RPM, voltmeters, and SIFA vigilance buttons. Over the years, the technology has evolved, and
