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.
