GoodApps / ParquetPeek

ParquetPeek

ParquetPeek opens Parquet files directly: schema browser, filters, sorting, row inspector, CSV export. For files where a Python script or a hosted BI seat is more than the job needs.

Availability: Free and open-source
Source code: View on GitHub
Replaces: a hosted BI seat
Platforms: macOS, Windows, Linux

What it does

Large-file friendly — Only the visible page loads at a time with pagination, so multi-gigabyte files stay snappy.
Schema & filters — Column search, one-click show/hide, type-aware filter builder, and click-to-sort on every column.
Inspect & export — Side row viewer with JSON trees, column stats, and CSV export of the current view.

Downloads

Choose your computer below to download the installer directly. Most Windows and Linux PCs use Intel / AMD. For Macs, check Apple menu → About This Mac: an Apple M-series chip means Apple silicon; an Intel processor means Intel.

Security warning: macOS and Windows may show an install prompt.

This app is not signed with a developer certificate. macOS may show an unidentified-developer or “damaged” alert; Windows may show SmartScreen. These prompts don’t establish whether the app is safe.
A “damaged” alert can be a false positive for an intact build, but may also mean the download is corrupt or altered. Download a fresh copy using the links above. If macOS still blocks the app and you trust the download, you can remove its quarantine flag using Terminal:
1. Drag the app into your Applications folder first.
2. Press Command + Space to open Spotlight, type “Terminal”, then press Return.
3. Copy and paste xattr -rd com.apple.quarantine into Terminal, then press the Space bar once. Don’t press Return yet.
4. Open Finder → Applications and drag this app into the Terminal window. This adds the app’s exact file path to the command.
5. Press Return to run the command, then open the app from Applications.
This removes the downloaded-app restriction for this app; it does not repair a corrupt download.
