Excel column unhide may sound trivial, but if you're preparing for a technical interview, live assessment, or remote screen-share test you should treat excel column unhide as a quick troubleshooting skill and a communication moment. This post explains when excel column unhide matters, how to do it in multiple scenarios, common pitfalls interviewers notice, and how to present the skill confidently under pressure.
Why does excel column unhide matter for interview preparation
On the surface, excel column unhide is a basic spreadsheet action — yet in interviews it can serve as a proxy for problem solving, attention to detail, and desktop fluency. For roles that require Excel (finance, accounting, data analysis), interviewers may set up a worksheet with hidden columns to test whether candidates notice anomalies or can recover data quickly. Even when not explicitly tested, being able to execute excel column unhide during a live screen share shows you can manage the tool without pausing the conversation.
It prevents awkward pauses when a required column is invisible during a live test.
It demonstrates that you can troubleshoot common worksheet issues (hidden columns, protected sheets, grouped data).
It helps you explain your steps clearly while sharing your screen — a communication skill interviewers value.
Key reasons to practice excel column unhide before interviews:
For official how-to mechanics, Microsoft documents the basic hide or show rows and columns commands that form the foundation for excel column unhide actions Microsoft Support.
How do you perform excel column unhide in different situations
There isn’t a single approach to excel column unhide — the right method depends on how the columns were hidden. Practice these common techniques so you can pivot fast in an interview.
Standard unhide for contiguous columns
Select the columns around the hidden range (e.g., click column headers B and D if C is hidden).
Right-click the selection and choose Unhide, or use Home > Format > Hide & Unhide > Unhide Columns.
This is the most common excel column unhide action and mirrors steps shown in official guides Microsoft Support.
Unhide all columns at once
Select the whole worksheet (Ctrl+A or click the top-left corner), then unhide.
Or use Format > Hide & Unhide > Unhide Columns to restore everything.
This approach is useful when multiple hidden columns exist; tutorials like those at GeeksforGeeks explain bulk unhide approaches for speed GeeksforGeeks.
Unhide the first column (A) or row (1)
The first column can be tricky because its header is left of the sheet. Microsoft details the special steps to unhide the first column or row when column A is hidden, such as dragging from the top-left corner or using Go To to select cell A1 and adjust column width Microsoft Support - First Column.
Hidden by grouping or outline
If columns are grouped (small +/- icons appear), click the plus sign or use Data > Ungroup to reveal them.
Grouped columns behave differently than manually hidden columns; check the Data ribbon.
Hidden by column width set to zero or sheet protection
If a column width is set to zero (looks hidden but not via Hide command), select the adjacent columns and drag the boundary to restore width or set width numerically.
If a sheet is protected, you may need to unprotect it (if authorized) before you can perform an excel column unhide.

What common mistakes happen when attempting excel column unhide during interviews
Knowing how to do excel column unhide is one thing; avoiding common mistakes under stress is another. Interview settings introduce pressures that cause small errors:
Trying to unhide without selecting adjacent columns: Right-clicking a single column header won't work if the hidden columns aren't within the current selection.
Missing grouped columns: Hidden columns due to grouping require a different action (click the outline symbol), which candidates sometimes miss.
Overlooking filters: Filtered views can make rows and columns appear missing; check filters before assuming a column is hidden.
Forgetting sheet protection: Protected sheets prevent unhide actions; attempting to change width without unprotecting leads to confusion.
Not checking view settings or frozen panes: Freeze panes and split views can make it seem like columns are hidden.
If you run into any of these during an interview, narrate your troubleshooting: “I’m checking for grouping, filters, protection, and column width” — this shows process and reduces the appearance of fumbling.
How can you explain your excel column unhide skills in an interview
Interviewers care about how you approach a problem, not just whether you know the command. Use excel column unhide as an opportunity to showcase methodical thinking.
Describe the checklist: “First I check filters, then grouping, then protection and column width, and finally use the unhide command or adjust column width.”
Use concise language: Say exactly which ribbon path or shortcut you’ll use so the interviewer follows your actions.
Tie to outcomes: Explain why you’re unhiding columns — to recover missing data, verify formulas, or prepare a report — and how that impacts deliverables.
Offer a faster alternative if appropriate: For bulk restores, mention selecting the whole sheet and unhiding everything as a time-saver.
This framing communicates that excel column unhide is not a rote trick but part of a disciplined troubleshooting approach.

How can you prepare for excel column unhide scenarios in remote interviews
Remote interviews add factors like screen sharing and nervousness. Practice these habits to handle excel column unhide smoothly:
Set up a clean test workbook with intentional hidden columns to practice unhide workflows and narration.
Memorize one or two keyboard shortcuts and the ribbon path so you can act without hunting menus.
Test screen sharing in advance and be ready to direct the interviewer: “I’ll unhide a column now so you can see the underlying formula.”
Keep a backup copy of the spreadsheet if you need to reset changes quickly.
If you cannot unhide due to protection or permission, explain the limitation and propose the next step (request permission, ask the interviewer to unprotect, or share a corrected file).
Practicing these actions reduces the cognitive load of remembering how to unhide and lets you focus on the analysis that matters in the interview.
