We make spreadsheet risk visible
SheetSift was built by developers who kept getting pulled into spreadsheet fires — broken formula chains, mystery hardcoded values, formulas referencing files that no longer exist, and workbooks last touched by someone who left the company two years ago.
Most companies have hundreds of Excel workbooks that are load-bearing infrastructure with no documentation, no tests, and no owner. SheetSift gives you a structured way to audit them — surface the risks, understand the dependencies, and prioritize the fixes.
What we scan
Broken references
Formulas pointing to missing ranges, deleted sheets, or #REF! errors
Hardcoded values
Magic numbers embedded in formulas that should be named inputs
Inconsistent formulas
Ranges where most cells share a pattern but outliers don't
Circular references
Dependency loops that silently produce wrong results
Volatile functions
NOW(), RAND(), OFFSET() — functions that recalculate on every change
External references
Links to other files that may have moved, been renamed, or deleted
Hidden elements
Hidden sheets, rows, and columns that carry undocumented logic
Key-person risk
Workbooks where a single person created and maintains everything
Staleness
Workbooks that haven't been touched in six months but are still in use
Built for teams, not just analysts
SheetSift translates technical findings into business language. Instead of "EXTERNAL_REFERENCE in cell B14", you get "this workbook depends on a file that hasn't been scanned" — with a risk grade, a remediation priority, and a downloadable assessment report you can hand to a manager.
Team plans add a portfolio view across your entire workbook estate — so you can see which files are your biggest liabilities, track risk trends over time, and triage by theme.
