DataRadar Help

What is DataRadar?

DataRadar is a browser-based data quality profiling tool designed for locked-down environments where you can't install software. All processing happens client-side in your browser using WebAssembly.

Supported File Formats

• CSV/Tabular: Any delimited text file (comma, pipe, tab, etc.)
• Excel: .xlsx, .xls, .xlsb, .ods formats
• JSON: Single JSON objects or newline-delimited JSON (NDJSON)

Report Types

• Data Quality (DQ): Shows patterns, frequencies, and examples for each column
• Character Profiling (CP): Analyzes individual character frequencies (useful for encoding issues)

Masking Levels

• HU (High Unicode): 'John123' → 'Aaaa999' - Detailed pattern matching
• LU (Low Unicode): 'John123' → 'A9' - Compressed patterns

Privacy Guarantee

Your data is processed entirely in your browser using WebAssembly. Nothing is uploaded to any server. You can even use DataRadar offline (after initial load). Perfect for sensitive data in NHS, councils, or regulated environments.

Use Cases

• Validating data exports before sharing with partners
• Checking data quality before warehouse loads
• Spotting encoding issues, nulls, or unexpected patterns
• Quick sanity checks on unknown datasets
