About Judgement Bands

Excel analysis Add-in 

See what your numbers are saying

Judgement Bands started as a tool I built for myself after realizing there had to be a better way.

​

Over the years, I have spent a lot of time in Excel reviewing numbers, comparing columns, looking for patterns, and trying to separate what matters from what is just noise. Excel is incredibly powerful, but I kept running into the same problem: it was too slow to turn raw numbers into clear visual judgment.

Conditional formatting helped, but it often felt fragile. Every workbook had its own rules.

 

Every column needed its own setup. And when the analysis grew, the spreadsheet became harder to read instead of easier.

​

I wanted something faster.

​

I wanted to define what Poor, Weak, Good, and Great meant for a column, apply it consistently, and instantly see what stood out.

​

So I built Judgement Bands.

​

Judgement Bands grew out of my interest in information visualization and my enjoyment of building practical software tools.

​

I have always been interested in how good visual design helps people understand information faster. A spreadsheet full of numbers can contain useful signals, but those signals are easy to miss when everything looks the same.

​

The goal was simple: make important patterns in spreadsheet data easier to see, without forcing people to leave Excel or learn complicated macros.

​

At first, it was just a personal tool I used to make spreadsheet review faster and clearer. It helped me apply consistent visual classifications and focus on the values that deserved attention.

Then I realized other Excel users probably had the same problem.

Many Excel users spend time reviewing columns of numbers, comparing values, looking for patterns, and trying to see what deserves attention. Judgement Bands was created to make that work easier.

It does not replace your judgment.

​

It helps you see your judgment.

​

You define the bands. Judgement Bands applies them clearly and consistently.

Built for practical Excel use

Judgement Bands is intentionally focused.

​

No bloated platform.


No complicated setup.


No moving your data somewhere else.

​

Just a practical Excel add-in that helps you turn columns of numbers into clear visual judgment.

Privacy-first by design

Judgement Bands works locally inside Excel.

​

Your spreadsheet data stays on your computer. The add-in does not upload your cell values, formulas, workbooks, or business data to us.

​

Why share it?

​

Because I built something that solved a real spreadsheet problem for me, and I believe it can help other people who live in Excel review, classify, and understand their data faster.

Selfie of creator.

Founder & Lead Developer

With over two decades of experience at the intersection of software development, enterprise architecture, and analysis, Clint Johnson has built software, led architecture teams, and designed enterprise platforms.

His experience spans desktop, web, mobile, cloud, and data technologies — from C#, WPF, C++, C++ MFC, and Objective-C to Swift, Node.js, Angular, Python, Java, AWS, SQL, and Data science with pandas.

Across that work, one theme kept showing up: people do not just need more data. They need clearer ways to see what the data means.

Judgement Bands grew out of that conviction. It brings together hands-on engineering and information visualization to help Excel users turn columns of numbers into clear, consistent visual judgment.

Building Judgement Bands also required persistence. Excel add-in development is technically demanding, especially when working deeply with workbook state, ranges, formatting, ribbon behavior, and Microsoft Office’s COM automation model. A lot of care went into making the add-in behave predictably, manage Excel resources properly, and stay out of the user’s way.
