Description
Analyze data instantly on web page tables, without leaving the page, without copying data, without Excel.
HiTable is a powerful browser extension that lets you perform instant, in-place statistical calculations on HTML tables directly in your browser. Drag to select cells and see statistics appear on all four sides — no more copying tables into Excel for basic computations.
=== FEATURES ===
Table Support:
• Standard HTML tables — including complex ones with merged cells (rowspan/colspan)
• Nested tables — tables inside tables, automatically flattened into one unified grid
• Div-based tables — CSS Grid / Flexbox layouts detected by class patterns and geometric analysis
• ARIA grids — elements with role="grid" or role="table" detected via semantic markers
15 Statistics Algorithms (4 groups):
• Basic: Count, Sum, Average, Minimum, Maximum, Range
• Advanced: Median, Standard Deviation, Variance, Mode
• Quantile: Q1 (25%), Q3 (75%), Interquartile Range
• Distribution: Skewness, Kurtosis
Conditional Formatting & Anomaly Detection:
• Three-scope detection: across selection, within each column, within each row
• Outlier values (>2× standard deviation) highlighted with slow pulsing animation
• Hover to see the reason and scope of each anomaly
• Toggle on/off in settings
Data Integrity Checks:
Six tests to spot potentially fabricated data:
• Benford's Law — first-digit distribution analysis
• Last Digit Analysis — detects uneven distributions (human bias)
• Rounding Preference — flags excessive 0/5 endings
• Duplicate Detection — unusually frequent values
• Ratio Anomaly — near-constant cross-column ratios
• Monotonic Sequence — over-linear sorted patterns
Number Format Recognition:
• Currency symbols: $, €, £, ¥, ₹, ₽, HK$, NT$
• Magnitude suffixes: K (×1,000), W/万 (×10,000), M (×1,000,000), 亿 (×100M), B (×1B)
• Full-width digit normalization (123 → 123)
• Statistical results auto-inherit currency prefix and magnitude suffix
Built-in Demo & Help Pages:
• 7 sample tables to try all features immediately
• Comprehensive help covering all features, available in 9 languages
