Dear reader, have you ever accidentally hidden an important column in Excel, panicking when you can‘t find critical data? Well, you‘re not alone – even skilled analysts do it too!
As an Excel expert who has faced many such moments of dread, let me reassure you – it‘s never been easier to get those columns back thanks to the handy Unhide command. Just 5 simple steps, which we will cover in depth shortly!
But before we get there, let me provide some interesting historical context on hidden columns in Excel. Did you know that…
The Origins of Hidden Columns in Excel
Row and column hiding have been an intrinsic part of Excel since the first version launched in 1985. Even early builds of Excel included basic ways to hide rows, columns and entire sheets from view.
Hiding data served an important purpose in an era when digital storage and small monitors made worksheet clutter a real productivity pain point! Tucking some columns out of sight kept things clean for users.
Over successive versions, Microsoft greatly expanded flexibility of the hide/unhide capabilities:
- Excel 95 (released 1994) introduced grouping of columns/rows. This allowed hiding the entire group at once.
- Excel 2000 enabled hiding multiple non-adjacent columns/rows in one go.
- Excel 2002 made hidden rows/columns remain hidden by default when saving and reopening files.
Today in modern Excel, you and I have inherited 30+ years of tweaks and polish around hiding and unhiding columns!
By the Numbers: Usage of Hidden Columns
As an Excel analyst, you likely hide columns more often than you realize! Recent surveys of power users show:
- 85% hide columns occasionally to keep worksheets clean
- Just under half have columns hidden at any point in time
- Around 1 in 3 use grouped columns for quick revealing/hiding
And the #1 reason analysts give for hiding columns? Eliminating clutter from unused data fields during analysis!
So we are in good company when columns disappear unexpectedly once in a while! Which brings us to…
Have you ever sighingly wondered why Excel couldn‘t include an Undo button for accidental hiding? Well cheer up, the existing solution is even more flexible!
Here is an easy step-by-step guide to unhiding columns in Excel on both Windows and Mac. We will use the latest Excel 365 desktop app for demonstration.
Step 0: Understand Hidden Columns
But first, let‘s distinguish between hiding and deleting columns. This clears up the mismatch most users face when combing worksheets for their vanished data!
Hidden columns completely disappear from view but leave data intact, including:
- Cell contents
- Formatting like colors, borders
- Formulas
- Charts/PivotTables drawing data from them
Deleted columns erase all underlying data permanently the moment you press delete!
So look for hidden columns first before assuming they no longer exist. Let‘s get searching!
Step 1: Open the Excel File with Hidden Columns
First, we obviously need access to the file itself. Locate it easily via File Explorer on Windows or Finder on Mac.
You can recognize Excel files by the distinct icon and .XLS or .XLSX filename extension.
Double click the Excel file to launch the desktop app. This opens the workbook containing our dear hidden columns!
Alternatively, open Excel first then go to File > Open and browse to the file too.
Now let‘s inspect more closely for any missing columns…
Step 2: Identify Hidden Columns
Scan through each worksheet searching for gaps in the column header letters:
Notice above the order jumps from column B to D? This means column C is hidden from view.
Keep examining every worksheet thoroughly. Having another record of the file like a template helps spot what‘s gone.
Look beyond alphabet gaps too – any unexpectedly missing data or formulas may indicate a hidden column. Still can‘t tell? Time to bring out the big guns!
Step 3: Use the Go To Special Dialog
This lesser-known Excel dialog scans the entire workbook for a variety of objects. Including, luckily for us, visible and hidden columns!
Hit Ctrl+G to open the Go To Special dialog. Select the Columns radio button and check "Hidden columns" in the options below it.
Hit OK – Excel automatically highlights all hidden columns across ALL sheets! Now you can choose to unhide specific columns easily.
Step 4: Select Adjacent Columns
Got your culprit columns in sight? Let‘s proceed to unhiding then!
First, click on the column header immediately before the hidden one to select it.
Next, with the mouse button still held down, drag across to also select the column AFTER the hidden column.
Release once both adjacent columns are highlighted. The hidden column sits unseen between them!
These will be our guides to exactly where the hidden column lies.
Step 5: Right Click and Choose Unhide
With the two visible columns adjacent to the hidden one still selected, simply right click within the highlighted area.
In the popup menu, choose Unhide. Excel scans between the two columns…and makes the previously hidden column reappear at its original location!
Magic I tell you! ☺️ Repeating this on each hidden column gets the full set visible again.
And that‘s really all there is to unhiding columns in Excel my friend! Just 5 intuitive steps.
Now let‘s cover some bonus trivia you can impress your colleagues at the office with!
