How audit-proof are Excel files in Versiobit?

Excel files – e.g., for income-expense reports, mileage logs, or cash books – can be archived in an audit-proof way with Versiobit.

When saving, Versiobit creates an immutable version of your file and permanently secures its hash in the public Ethereum blockchain. Any further changes create new versions, which are also individually secured.

A maximum of one version per file per day is stored. So, with daily edits, up to 365 versions per year can be created – each immutably documented.

Previous versions remain accessible and traceable. This allows you to verify:

• when a specific version existed,
• whether content was removed or altered.

This approach supports GoBD requirements for immutability and traceability – especially when relevant changes are regularly saved.

Conclusion: Even Excel files with ongoing entries can be maintained in an audit-proof manner with Versiobit.
