Check your Excel model for the mistakes investors find first.

Drop an .xlsx file. In a few seconds you get the formulas that break the pattern of their row, numbers typed into formulas, broken references and error cells. Your file never leaves your computer — the check runs locally in this page.

No model at hand? Run it on our sample SaaS model.

What it checks

Inconsistent formulas

A cell whose formula differs from the rest of its row — the classic “someone fixed one month by hand”.

Hard-coded numbers

Constants typed inside formulas (×0.02, +5000) instead of links to the assumptions sheet.

Broken references

#REF!, #DIV/0!, #N/A and other error results that silently zero your totals.

Sums that stop short

SUM ranges shorter than the neighbouring ones — a dropped month in an annual total.
