Lab Mode — Validate, Analyze & Transform Table Data

Validate CSV and HTML tables for structural errors, analyze column statistics and data patterns, and apply batch transformations — all locally in your browser. Your data never leaves your device.

What you can do

• CSV validation — detect missing fields, type mismatches, and duplicate rows
• Column statistics — count, min, max, unique values, null rate
• Data pattern analysis across rows and columns
• Batch transformation and data cleaning operations
• Runs entirely in the browser — no data uploaded
