The spreadsheet was not the problem. The process outgrew it.

A spreadsheet can solve a problem well for years. Trouble starts when it stops being a tool and becomes the place where the entire operation lives.

It rarely happens overnight. Another tab appears, then another copy, then a temporary column becomes permanent. Eventually the fastest way to learn what is happening is to ask who has the good version.

That does not mean spreadsheets are bad. It means the process grew.

The warning signs are usually boring

The same data gets entered more than once. One person knows which columns nobody should touch. Two files show different totals. An approval depends on a chat message. A report takes longer to prepare than to analyze.

When several of these happen together, you are no longer looking at a spreadsheet. You are looking at an improvised system.

Do not replace a spreadsheet just for the sake of replacing it

If part of the work still runs well there, keep it. Find the point where friction begins: who enters the data, who validates it, which source wins and which exceptions matter.

Sometimes the answer is new software. Sometimes it is an integration. Sometimes one process needs to leave the spreadsheet while everything else stays.

Our rule is simple: what works stays; what gets in the way gets fixed; what is missing gets built.
