How It Works

Troubleshooting

Extension Not Loading Files

Solution:

1. Restart VS Code
2. Check if the file is a valid Parquet file
3. Run Parquet Viewer: Show Logs to see detailed error messages

Large Files Loading Slowly

Solution:

• For files larger than 1GB, consider using a more powerful machine
• The extension automatically paginates data for better performance

Behind Corporate Proxy/Firewall

If extension fails to load:

1. Configure your system proxy settings for VS Code
2. Check if your firewall allows VS Code extensions
3. Check logs with Parquet Viewer: Show Logs

General Issues

1. Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P)
2. Run Parquet Viewer: Show Logs to see detailed error messages
3. Try reloading the window (Developer: Reload Window)

Privacy & Data

• All data processing happens locally on your machine
• No data is sent to external servers
• The extension only accesses the Parquet files you explicitly open
• No telemetry or data collection

Known Limitations

• Very large files (>1GB) may take longer to load
• Some complex nested Parquet schemas may not display optimally
