Spreadsheets are useful until they become infrastructure. Then they become fragile infrastructure nobody admits is infrastructure.
The problem is not that someone made a spreadsheet. The problem is that the spreadsheet became the place where business logic, manual corrections, hidden formulas, and unofficial truth now live.
The warning signs
- Reports depend on one person's file.
- People copy exports between systems every week.
- Several versions of the same spreadsheet circulate.
- Nobody knows which formulas changed.
- The file is too important to delete but too fragile to trust.
The practical next step
Do not try to replace every spreadsheet at once. Pick the workflow with the highest operational pain: monthly reporting, account lists, delivery tracking, revenue reconciliation, or customer matching. Map the sources, automate the movement, and create one trusted output.
The goal is not to ban spreadsheets. The goal is to stop using them as invisible production systems.
