No technical skills needed. Upload your data and get clear answers.
We compare each row to the rest and highlight what's different. "This is five times higher than typical."
See totals by month, by vendor, by employee - then spot which groups stand out from the rest.
Define your own ratios (like Expense ÷ Revenue) and find the rows where the ratio is unusual.
Your data never leaves your computer. No uploads, no servers, no cloud. Period.
"This amount is three times higher than average" - not math formulas. Anyone can understand.
Download your findings to Excel or CSV with all the details included.
Drop your Excel or CSV file. We support any spreadsheet format.
Choose the columns you care about (like Amount, Quantity, etc.)
Get a prioritized list with plain English explanations for each finding.
One score that sees all your metrics at once — no black box, just proven math.
We convert every value to a Z-score — how many standard deviations from the average. This makes all columns comparable, whether it's dollars, quantities, or percentages.
For each row, we add up the Z-scores from ALL selected columns. This creates one number that reflects how unusual the row is across everything.
Rows with the highest composite score rise to the top. These are the rows that stand out the most when looking at ALL your metrics together.
Each column is colored from light (normal) to dark (high). Scan a row: multiple dark cells = multiple unusual values = higher rank.
Z-scores are used by data scientists, auditors, and analysts worldwide.
No hidden algorithms. Normalize, combine, rank — that's it.
Export to Excel with all values visible. Check any number.
All calculations happen in your browser. No data sent anywhere.
