Hi Dzaki Gunawan,
Thanks for reaching out to Microsoft Q&A Forum. The “TRUE/FALSE” you’re seeing is the value of the checkbox’s linked cell, that part is expected, but the fact that the checkbox isn’t clickable points to one of a few common causes. Below are quick checks and fixes you can try; they’re ordered from most likely to fastest to resolve.
1) If you opened the file in a browser
Excel for the web doesn’t allow interacting with Form Controls or ActiveX checkboxes.
Fix: In the ribbon, choose Open in Desktop App (or open the file directly in Excel for Windows/Mac).
2) “Design Mode” is on (ActiveX checkboxes only)
When Developer → Design Mode is enabled, ActiveX controls are not clickable.
Fix: Go to Developer tab and make sure Design Mode is off.
3) Objects are hidden at the workbook level
If objects are hidden, shapes/controls (including checkboxes) can’t be interacted with.
Fix: File → Options → Advanced → Display options for this workbook → For objects, show: select All.
4) Sheet/workbook protection prevents editing objects
Protected sheets can block clicking controls if Edit objects isn’t allowed.
Fix: Review → Unprotect Sheet (enter password if there is one).
If you need protection on: Review → Protect Sheet, tick Edit objects before protecting.
5) File location/security blocking ActiveX
Files downloaded from email or the internet may have ActiveX blocked.
Fix: Right‑click the file in Explorer → Properties → check Unblock → OK.
Move the workbook to a trusted folder on your local drive (e.g., C:\TrustedExcelFiles) and reopen.
Or, replace ActiveX checkboxes with Form Controls (simpler and more reliable).
Recommended (robust) setup with Form Control checkboxes
6)If your current checkboxes are ActiveX, consider switching to Form Controls:
Fix: Developer → Insert → Form Controls → Check Box.
Place the checkbox on the cell (hold Alt while dragging to snap to cell grid).
Right‑click → Format Control → Control tab → Cell link → pick a helper cell (this cell will show TRUE/FALSE).
