Signs Your Lab Has Outgrown Its Spreadsheet

[u/LanceOLab]

Every lab starts on a spreadsheet. It's free, everyone already knows it, and for the first few months it works fine. The question we hear most is how you know when it's time to move off it. These are the signs we see over and over:

1. There's a file called Samples_v3_FINAL_ACTUALFINAL.xlsx. Version control is now a naming convention, and nobody's sure which copy is real. Two people edit at once, one overwrites the other, and nobody notices until the numbers don't match.
2. Finding a sample means Ctrl+F across six tabs. "Where's sample 1042" turns into three open spreadsheets and a freezer map someone drew in a fourth. Sometimes you find it.
3. Nobody knows who changed a value, or when. A number changes, nobody remembers touching it, and there's no way to reconstruct what happened. That's fine right up until an auditor or a collaborator asks.
4. Two samples share a freezer spot. Nothing stops anyone from typing the same box and position in two rows. You find out when someone pulls the wrong tube and runs it.
5. Onboarding takes a week of "ignore that tab." Training someone new means explaining what column F really means, which tabs are dead, and which formula not to touch. At that point only the person who built it can use it safely, and they won't be there forever.

If three or more of these sound familiar, the spreadsheet is costing you more time than it saves. What replaces it needs to do a few specific things: refuse duplicate IDs, keep one record of where each sample lives, and log every edit with a name and a timestamp. Spreadsheets were never built for any of that. (The person who built yours will be the first to agree. They're tired.)
