Welcome to the next generation of Benford Bench — an online data assessment & publishing tool for research in fraud and disorder detection using Benford's Law digit analysis.


Upload CSV for Digit Analysis

How it works: Upload a CSV file containing numeric data. Select the column to analyze. Benford Bench will apply first-digit (and other) analysis, compute chi-square and MAD statistics, and generate a full fraud-risk assessment report.
Data File

Which column contains the numbers to analyze (1 = first column).
Check this if the first row contains column names, not data.
First digit is most common for fraud detection. Second digit adds confidence.
Optional. Attach a supporting FOIA or source document (PDF).
