Spreadsheet Editor
We haven’t built an Excel competitor. We’ve built a Controlled Data Environment where every change is accounted for.
The Data Integrity Lifecycle
Spreadsheet tools are built on trust. We build on a more rigorous assumption:
Every cell matters, and every change must be accounted for.
This is the data lifecycle engineered for integrity from the first cell to the final audit.
From the moment you launch our spreadsheet, you are working in a sandbox, completely disconnected from the Internet. The calculations, formulas, and data you input are all processed entirely on your local machine. There is no risk of your sensitive financial models or case data being intercepted, because they never leave your device.
A standard spreadsheet shows you the final result; our Secure Spreadsheet shows you the entire journey. Our audit trail creates a permanent, time-stamped record for every significant change—from value and formula changes to cell redactions. This prevents any dispute about how a final number was calculated. You can prove, step-by-step, that a total was derived from the correct cells and not manually overwritten.
Because of this rigorous, real-time audit, you aren’t just presenting a set of numbers—you are presenting a set of numbers with a verifiable, unalterable pedigree. You can answer not only "What is the total?" but also "How was this total calculated, who made the last change, and when did they do it?"
When data must be shared, you have two secure options: export a “clean” version where redacted cells are permanently stripped, or seal the spreadsheet and its complete audit trail inside a Secure Document Container (.sdc) for maximum integrity.
The Bottom Line
You choose our Secure Spreadsheet when the precision and history of your data are as important as the data itself. A financial firm modeling a confidential acquisition; a forensic accountant tracing illicit funds; a law enforcement agency ensuring an unbroken chain of custody for evidence.
Every cell matters, and every change
must be accounted for.
We are not selling a better calculator.
We are selling verifiable truth.
