Signs a spreadsheet has stopped working
None of these mean the spreadsheet was a bad choice. They mean the records have outgrown a flat, tab-based structure and need something that understands relationships between records natively.
- More than two or three tabs cross-referencing each other
- You have stopped trusting whether a formula updated correctly
- Entering a record on your phone standing in the barn is awkward or impossible
- You keep meaning to build a "dashboard" tab and never finish it
- Finding one animal or machine's full history means checking multiple tabs
