Every number that changed. Marked in red.
Upload two versions of a model, a budget, a supplier price list — GridDiff isolates every change (values, formulas, rows) and explains it in plain language.
The real grid, with real data
A real excerpt from a comparison — take a few seconds to look.
Four types of change, always kept distinct
Changed values and formulas
Numbers and text changed cell by cell. Formula changes are flagged separately, since a change there can affect other numbers in the sheet too.
Added rows
Detected even when the sheet's row order has changed.
Removed rows
What used to be there and isn't anymore.
Added or removed sheets
See right away if a sheet is missing or a new one appeared.
The problems a naive comparison misses
Moved rows are still recognized.They don't trigger a cascade of false changes.
Formula or value — never the same risk. We always tell them apart, cell by cell.
The blackline you'd expect before signing off — not an approximate comparison.
Your files stay yours
GridDiff processes the two files you upload and deletes them right after showing the comparison — never stored on our servers, regardless of plan. Built for people who work with data they can't afford to expose: budgets, financial models, due diligence documents.
