Finding hidden information in Excel

Excel enables users to hide things, such as rows, columns, formulas, and even whole sheets. This is often done to simplify the “workings” of the model for users that might be less familiar with its structure, or users that simply don’t need to see everything to work with the file. In many cases it’s actually quite a clever solution in which users just see the few cells or sheets that are relevant to them.

Risks of hidden information

Issues appear when something stops working. For example, if a user unexpectedly adds a column that they weren’t supposed to, runs into an error, and, in attempt to remedy the situation, accidentally deletes or moves crucial information without knowing what they’ve done! On top of all that, the original creator of the spreadsheet might have left the company with little to no documentation on how this model actually works.

Finding hidden information (even very hidden worksheets)

It’s clear that finding hidden information in the spreadsheet you are working with might be crucial to understand its workings. Our tool PerfectXL Explore visualizes the structure of the model, giving you access to all connections between worksheets and showing you exactly where hidden worksheets are and what they are doing. Our tool even reveals very hidden sheets which are not possible to reveal with standard Excel (without VBA).

In PerfectXL Explore a model looks something like this:

You can also access a list of all worksheets and sort by visibility:

The links on the right (in green) allow you to either unhide and open the worksheet in Excel, or to see all links to that sheet in your model. This allows you to understand how these hidden worksheet are interacting with the rest of your model.

As with most things in Excel, this isn’t some “quick hack”. You’ll still have to roll up your sleeves and get to work, but like most battles, in this case knowing is half the battle!

Numbers without meaning are worthless. Excel is a program for numbers, but it is only useful if it is clear to the reader or user what these numbers mean. So, make sure that you provide textual information for all data and formulas, let’s call these pieces of text information labels.
