Checkboxes are not saved to pdf

My ExcelFile has a number of checkboxes the user can click.
In the attachment, the first example.

When opening this file and saving it to pdf these checkboxes are ignored.
In the attachment, the second example.

I want these checkbox controls saved like Excel does.
In the attachment, the third example.

Does Gembox.Spreadsheet support this ?
If so, what do I need to do to make it happen ?

Hi Frank,

Unfortunately, GemBox.Spreadsheet currently doesn’t export checkboxes to output PDF.

Note that we have an internal support ticket in which we keep track of this feature’s priority.
Also, note that we do plan to add support for this in the future after its priority is increased (more users request it).
For now, I’m afraid I cannot say exactly when that could be.


Hi Frank,

Note that Form Controls (not the ActiveX Controls) should be rendered to PDF output.
So, please try again with this bugfix:

Or this NuGet package:
Install-Package GemBox.Spreadsheet -Version 49.0.1178-hotfix

Also, if you’re running on Linux please add the “Segoe UI Emoji” font so that checkbox symbols can be properly rendered.

I hope this helps.
