The Spreadsheet You Trust Most Might Be Lying to You
Why Nobody Catches It
Where This Actually Happens

A formula that references the wrong row or column after a new line was inserted, silently pulling in the wrong figure from that point forward.

A manually typed number that was never linked to source data, meaning it's frozen at whatever value someone entered once, regardless of what's actually changed since.

A copied formula that didn't adjust correctly, quietly repeating an error across dozens of cells that all look individually fine.

Multiple versions floating around, where different people are working from different copies, each believing theirs is the current, accurate one.
What to Actually Check
- When was the last time someone independently verified your key spreadsheet's output against the actual source records, rather than just trusting the output?
- Are critical figures linked to live data, or manually typed and potentially stale?
- Is there one single, clearly identified master version, or several copies that might have quietly diverged?
The businesses that get caught out aren't the ones with obviously bad spreadsheets — they're the ones with a spreadsheet everyone trusted a little too much for a little too long.
