Excel add-in that makes Excel formulas easy to understand, check, troubleshoot and fix.

X-ray for Excel formulas

Instantly understand and troubleshoot complex Excel formulas

SEE FORMULA STEPS AND CALCULATIONS
The horizontal view displays the result of each part of a formula in order to see how the result is calculated. You can also expand and collapse the formula parts by clicking the green result bar.

The vertical view displays a formula as a tree of the parts of a formula. The parts can be expanded and collapsed.

PINPOINT ERRORS INSTANTLY
Excel tells you when a formula has an error, but that’s it. Long formulas are even worse…where do you even start to track down the problem?

Now, FormulaSpy will pinpoint EXACTLY where the error is – no more guessing or wasting hours of your precious time.

DRILLDOWN INTO REFERENCED CELLS (PRECEDENTS)
Explore the cells that the formula uses, visit them and see their formulas, then drill into their references to gain a deep understanding of the entire calculation chain.
