Clean That Sheet Guard is like spell check for Google Sheets. It works alongside you to catch spreadsheet problems before they become bigger mistakes. Check for duplicates, blanks, formatting issues, import mismatches and more with modes like Safe to Send and Import Ready. Your original sheet stays intact, and you get 10 free cleanups to try it.

Hey Product Hunt 👋 I built Clean That Sheet because I kept running into the same problem: spreadsheets can look completely fine while small mistakes are hiding inside them. A duplicate row, blank field, formatting mismatch, or data that doesn’t match an import template can turn into a much bigger headache later. That eventually led me to build Clean That Sheet Guard, a Google Sheets add-on that works more like spell check for your spreadsheet. Instead of waiting until something goes wrong, Guard gives you a second set of eyes while you’re working. One of my favorite features is Import Ready. You can place an import template in one tab and your data in another, and Guard checks whether the data is actually ready before you upload it somewhere else. This has been a very bootstrapped build, so I’m excited to finally put it in front of the Product Hunt community. I’d especially love to hear what spreadsheet problems you run into that you wish software caught automatically.

One thing I ve learned while building Clean That Sheet Guard is that spreadsheet problems often don t become obvious until the data moves somewhere else.

A CRM import fails.
A payroll upload rejects rows.
A CSV doesn t match the required template.
Duplicate contacts suddenly appear in another system.

By that point, the spreadsheet that caused the problem is already upstream.

That s a big part of why I built Guard to work directly inside Google Sheets and catch things like duplicates, blanks, formatting inconsistencies, and template mismatches before the data gets handed off.
