AI Governance

AI can draft the numbers. You stay in control.

Gridbox and our Excel add-ins give finance teams the checks and records auditors expect, before any figure reaches a report.

Every change on record

See who changed what and when. Each figure traces back to its source data and its formula.

People approve, not AI

AI suggestions are reviewed in Excel, with comments and sign-off, before they go into a model.

Audit-ready by default

Automatic error checks and version comparisons give you the evidence for audits and regulatory reviews.

Increase your productivity

to a colleague?

In the age of AI, spreadsheet review matters more than ever.
Don’t build black box models.
